A marshmallow is placed in a microwave to be heated for smores. The marshmallow has a 86 mL at a temperature of 543 °C. What temperature, in K, would the
marshmallow need to be if the volume changed to 51.1 ml?

Answers

Answer: 484.94 K

Explanation:

T2 = T1 X V2 / V1

Temperature must be in kelvin so 543 + 273.15 =816.15

816.15 X 51.1 / 86

Answer: We can use the combined gas law to solve this problem:

(P₁V₁/T₁) = (P₂V₂/T₂)

where P is pressure, V is volume, and T is temperature in Kelvin.

We know that P₁ = P₂ (the pressure is assumed to be constant), and we are given V₁, T₁, and V₂. We can solve for T₂:

(P₁V₁/T₁) = (P₂V₂/T₂)

T₂ = (P₂V₂/T₁) * (T₁/P₁V₁)

We need to convert the initial temperature from Celsius to Kelvin:

T₁ = 543 + 273 = 816 K

Substituting the values:

T₂ = (1 atm * 86 mL / 816 K) * (51.1 mL / 1 atm * 86 mL)

T₂ = 0.0629 * 51.1 * 1000 = 3217 K

Therefore, the marshmallow would need to be heated to a temperature of 3217 K for its volume to change from 86 mL to 51.1 mL.

A gummy bear has a mass of about 2.3 g and a volume if about 1 mL. About 12% of the mass of the gummy bear is sugar. Estimate the sugar concentration in a gummy bear.

Answers

To estimate the sugar concentration in a gummy bear, we first need to determine the mass of sugar in the gummy bear.

Given that the gummy bear has a mass of 2.3 g and 12% of its mass is sugar, we can calculate the mass of sugar in the gummy bear as follows:

Mass of sugar = 12% x 2.3 g = 0.276 g

Next, we need to convert the volume of the gummy bear to liters, since concentration is typically expressed in units of moles per liter. Since 1 mL = 0.001 L, the volume of the gummy bear is:

Volume of gummy bear = 1 mL = 0.001 L

Now we can calculate the sugar concentration in the gummy bear in units of moles per liter. The molar mass of sugar is about 342 g/mol, so the number of moles of sugar in the gummy bear is:

Number of moles of sugar = 0.276 g / 342 g/mol = 0.000807 mol

Therefore, the sugar concentration in the gummy bear is:

Sugar concentration = number of moles of sugar / volume of gummy bear

= 0.000807 mol / 0.001 L

= 0.807 mol/L

So, the estimated sugar concentration in a gummy bear is 0.807 mol/L.

Answers

The half-life for the reaction is 0.693/k. It will take approximately 1.386/k seconds for the concentration of A to decrease to 25% of its initial concentration. It will take approximately 2.218/k seconds for the concentration of A to decrease to 0.78 M. If the initial concentration of A is 0.150 M, the concentration of A after 5 half-lives is 0.00938 M, and after 10 half-lives it is 0.00059 M.

The decomposition of A is a first-order reaction with a rate constant of k at a certain temperature. The rate law for this reaction is given by:

Rate = k[A]

The half-life for a first-order reaction is given by the equation:

t1/2 = 0.693/k

Substituting the given rate constant into this equation gives the half-life for the reaction.

To calculate how long it will take for the concentration of A to decrease to 25% of its initial concentration, we can use the equation:

[tex]ln\frac{A_{t} }{A_{0}} = -k_{t}[/tex]

Substituting 0.25[A]0 for [A]t and the given rate constant into this equation, we can solve for t.

Similarly, to calculate how long it will take for the concentration of A to decrease to 0.78 M, we can use the same equation and substitute 0.78 M for [A]t and the given rate constant into the equation.

To determine the concentration of A after a certain amount of time has passed, we can use the equation: [A]t = [A]₀ [tex]e^{-kt}[/tex]

Substituting the given rate constant and the time elapsed into this equation will give us the concentration of A at that time.

An intoxicated driver has 12ml ethy alcohol in his blood. Calculate molarity

Answers

The molarity is 0.000052 Molar for an intoxicated driver who has 12ml ethyl alcohol in his blood.

We must be aware of the molecular weight of ethyl alcohol to compute molarity (C2H5OH).

Ascertaining the atomic weight of C2H5OH yields the accompanying outcomes: (1 x 16.00 g/mol for oxygen) + (2 x 12.01 g/mol for carbon) + (6 x 1.01 g/mol for hydrogen) = 46.07 g/mol

We presently need to realize how much blood the 12 ml of ethyl liquor break up to decide the molarity of ethyl liquor in the driver's blood. Expect the driver to have a blood volume of 5 liters generally speaking (5000 ml).

To get the quantity of ethyl alcohol in moles, multiply 12 ml by (1 L/1000 ml) x (1 mol/46.07 g) to get 0.00026 mol.

It is possible to compute the amount of ethyl alcohol in the driver's blood as follows: 0.00026 mol/5 L = 0.000052 M

The amount of ethyl alcohol in the driver's blood is thus 0.000052 Molar.

The reaction system CO(g) + 2 H2(g) = CH3OH(g) is at equilibrium. When H2 is added to the container, the reaction shifts to the right the partial pressure of Co does not change and the partial pressure of CH3OH decreases

Answers

The reaction system CO(g) + 2 H2(g) = CH3OH(g) is at equilibrium, meaning that the rate of the forward reaction is equal to the rate of the reverse reaction. If H2 is added to the container, the forward reaction becomes favoured and shifts to the right. This increases the amount of products (CH3OH) formed, and decreases the amount of reactants (CO and H2). As a result, the partial pressure of CO remains the same, while the partial pressure of CH3OH decreases.

This is due to Le Chatelier's Principle, which states that when a system at equilibrium is subjected to an external stress, the system will adjust to minimize the stress. In this case, the stress is the addition of H2, which is favouring the formation of products and disrupting the equilibrium. The system responds by decreasing the amount of products formed and shifting the reaction back to equilibrium.

9.0 moles of Na3PO4 will form from 9.0 moles of H3PO4, rounded to the tenths place.

How to solve

To determine how many moles of Na3PO4 form from 9.0 mol H3PO4, we need to use stoichiometry.

First, we'll identify the mole ratio between H3PO4 and Na3PO4 in the balanced chemical equation:

3NaOH + H3PO4 → 3H2O + Na3PO4

From the balanced equation, we can see that the mole ratio between H3PO4 and Na3PO4 is 1:1.

This means that for every 1 mole of H3PO4 reacted, 1 mole of Na3PO4 is produced.

Since we have 9.0 mol H3PO4:

9.0 mol H3PO4 * (1 mol Na3PO4 / 1 mol H3PO4) = 9.0 mol Na3PO4

So, 9.0 moles of Na3PO4 will form from 9.0 moles of H3PO4, rounded to the tenths place.

the concentration of o2 in water is 0.590g per liter at an oxygen pressure of around 15.5 atm. what is the henry's law constant for o2

Answers

The Henry's law constant for O2 in water given the concentration of O2 in water is 0.590 g/L and an oxygen pressure of around 15.5 atm is 4.42 x 10^-4 M/atm.

Henry's Law relates to the concentration of a gas dissolved in a solvent to the pressure of that gas in equilibrium with the solvent. According to Henry's Law, the concentration of gas in a liquid is directly proportional to the partial pressure of the gas in the atmosphere over the liquid. The law is as follows: c = kPwhere c is the concentration of the gas in the liquid, P is the partial pressure of the gas in the atmosphere over the liquid, and k is a proportionality constant known as the Henry's law constant. To find the value of Henry's Law constant for O2 in water, we will use the formula: k = c / P Given that the concentration of O2 in water is 0.590 g/L and the oxygen pressure is 15.5 atm, we can substitute these values to find the value of Henry's law constant. k = c / Pk = (0.590 g/L) / (15.5 atm)k = 0.038 M/atm

why is the reaction rate for reactants defined as the negative of the change in reactant concentration with respect to time, whereas for products it is defined as the change in reactant concentration with respect to time (with a positive sign)?

Answers

The reason why the reaction rate for reactants is defined as the negative of the change in reactant concentration concerning time, whereas for products, it is defined as the change in reactant concentration concerning time (with a positive sign) is because a reaction rate is a measure of the speed at which a reaction takes place.

Let's understand it in depth:

The reaction rate is determined by how fast the reactants are being used up or consumed and how quickly the products are being formed. If the reactants are being used up rapidly and the products are being formed slowly, the reaction rate will be slower than if the reactants were being used up slowly and the products were being formed rapidly. In general, the rate of a chemical reaction is expressed as the change in concentration of one or more of the reactants or products over a given time.

To calculate the reaction rate, you need to measure the change in concentration of one or more of the reactants or products over time. If the concentration of the reactant decreases over time, the reaction rate is expressed as a negative number. On the other hand, if the concentration of the product increases over time, the reaction rate is expressed as a positive number.

assuming you have an agonist, a competitive antagonist, and an easy assay for measuring binding of the agonist, describe a simple experiment that would allow you to determine specific binding, nonspecific binding, and total binding of the agonist at a single concentration.

Answers

A simple experiment to determine the specific binding, nonspecific binding, and total binding of an agonist at a single concentration would involve the following steps:

1. Pre-incubate a set of samples containing the agonist and various concentrations of the competitive antagonist. This will allow you to calculate the fractional inhibition of binding (FIB) of the agonist by the antagonist.

2. Use the easy assay to measure the binding of the agonist to its target. This will give you the total binding of the agonist.

3. To calculate the nonspecific binding of the agonist, subtract the total binding from the FIB. This will give you an estimate of the amount of agonist that binds to sites other than the target.

4. Finally, to calculate the specific binding of the agonist, subtract the nonspecific binding from the total binding. This will give you an estimate of the amount of agonist that binds to its target.

Compose the cathode and anode processes of melt electrolysis of MgS, the total electrolysis equation

Answers

Answer:

The electrolysis of MgS by melt electrolysis involves the use of a molten salt as the electrolyte. The cathode and anode processes and the overall electrolysis equation are as follows:

Cathode: Mg2+(l) + 2e- → Mg(l)

Anode: S2-(l) → S(g) + 2e-

Overall: MgS(l) → Mg(l) + S(g)

At the cathode, magnesium ions (Mg2+) are reduced to magnesium metal (Mg) by gaining two electrons (2e-) from the cathode. This process occurs due to the higher reduction potential of Mg2+ compared to S2-.

At the anode, sulfide ions (S2-) are oxidized to sulfur gas (S) and electrons (e-) by losing two electrons. This process occurs due to the higher oxidation potential of S2- compared to Mg2+.

The overall electrolysis equation shows that magnesium sulfide (MgS) is broken down into magnesium metal (Mg) and sulfur gas (S) by the application of an electric current.

It's worth noting that molten salt electrolysis is commonly used for the production of metals such as aluminum and magnesium, as it allows for the separation of the metal from its ore in a relatively efficient manner. However, the high temperatures required for melt electrolysis mean that it can be an energy-intensive process.

The definition of effusion is the leakage of gas molecules from a container through a tiny hole.

Effusion refers to the process by which a gas flows through a tiny hole in a container into an area of lower pressure. The rate of effusion can be influenced by factors such as the size of the hole, the mass of the gas molecules, and the temperature of the gas. In effusion, the gas molecules move from an area of higher pressure to an area of lower pressure.

The rate of effusion is influenced by several factors, including the size of the hole, the mass of the gas molecules, and the temperature of the gas. The rate of effusion is directly proportional to the average velocity of the gas particles. Therefore, lighter molecules will effuse faster than heavier molecules. The average distance travelled by a particle between collisions is called mean free path while the spreading of gas molecules through space is called diffusion.

Will a supersaturated solution return back to being a saturated solution once a solute crystal has been added?​

Answers

Yes, a supersaturated solution will return back to being a saturated solution once a solute crystal has been added.

Supersaturated solution explained.

A supersaturated solution is a solution that contains more dissolved solute than would be possible under normal circumstances at a given temperature and pressure. In a supersaturated solution, the solute molecules are able to remain dissolved in the solvent even though they would normally begin to precipitate out of the solution. This can happen when a solution is prepared by dissolving a solute in a solvent at an elevated temperature and then cooling the solution rapidly, preventing the solute from crystallizing out of the solution. Supersaturated solutions are often unstable and will eventually return to a saturated state if given the opportunity to do so, such as by the addition of a seed crystal or agitation of the solution.

When a solute crystal is added to a supersaturated solution, it provides a nucleation site for the solute to crystallize. As the solute molecules attach to the crystal, they are removed from the solution, causing the concentration to decrease. Eventually, the concentration will decrease to the point where it becomes saturated, and no more solute will dissolve.

Thus, adding a solute crystal to a supersaturated solution causes the excess solute to come out of the solution and return it to a saturated state.

To find the number of moles of NaClO added to the solution, we need to multiply the concentration by the volume:

moles NaClO = concentration x volume

moles NaClO = [tex]3.162 \times 10^{-11} mol/L \times 2L[/tex]

moles NaClO = 6.23 × [tex]10^{-11}[/tex] mol.

Therefore, the number of moles of NaClO that were added to the water is 6.23 × [tex]10^{-11}[/tex] mol..

which has the most atoms? 20g C or 70g Zn

Answers

Therefore, the 20g of C has more atoms than the 70g of Zn.

How is number of atoms determined?

To determine which sample has the most atoms, we need to use Avogadro's number, which is the number of atoms in a mole. Avogadro's number is approximately 6.022 x 10^23 atoms/mole.

First, we need to determine how many moles of each substance we have. We can do this by dividing the given mass by the molar mass of the element. The molar mass of carbon (C) is approximately 12 g/mol, and the molar mass of zinc (Zn) is approximately 65 g/mol.

For 20g of C:

moles of C = 20 g / 12 g/mol ≈ 1.67 moles

For 70g of Zn:

moles of Zn = 70 g / 65 g/mol ≈ 1.08 moles

Now, to determine the number of atoms, we can multiply the number of moles by Avogadro's number.

For 20g of C:

number of atoms = 1.67 moles x 6.022 x 10^23 atoms/mole ≈ 1.00 x 10^24 atoms

For 70g of Zn:

number of atoms = 1.08 moles x 6.022 x 10^23 atoms/mole ≈ 6.50 x 10^23 atoms

Therefore, the 20g of C has more atoms than the 70g of Zn.

How many g of water are needed to create a 4 molal solution with 9 moles of naOH

Answers

To make a 4 molal solution using 9 mol of NaOH, we need 2250 g of water.

How can the mass of water needed to make a 4 molal solution with 9 mol of NaOH be calculated?

NaOH mass equals moles of NaOH times its molar mass, or 360.00 g.

Molality is defined as moles of solute divided by kilograms of solvent.

When we rewrite the equation, we obtain:

mass of the solvent is equal to the product of the solute's moles and its molality.

Inputting the values provided yields:

mass of the solvent equals 9 mol/4 mol/kg

2.25 kg is the solvent's mass.

The mass of water is then converted from kilogrammes to grammes:

2.25 kg times 1,000 g/kg is the mass of water.

water weighs 2250 g.
