Explanation:

The cryosphere—the portion of the Earth's surface where water is in solid form for at least one month of the year—has been shrinking in response to climate warming. ... The important outcome, however, is the change and the response the human social system (infrastructure, food, water, recreation) will have to that change.

The cryosphere the portion of the Earth's surface where water is in solid form for at least one month of the year has been shrinking in response to climate warming.

The cryosphere includes all of the earth's frozen water, including glaciers and sea ice.

The lithosphere is the solid part of the earth made up of rocks, minerals, and other elements except the ocean. It is the  part which present in the outer part of the earth which includes the brittle upper portion of the mantle and crust. The part of  planet where living things can be found from the upper part of the atmosphere to the lower of the oceans and pools that are thermal and made up of the parts of earth where life present in all ecosystem is known as biosphere.

The atmosphere is the thin layer of gases that covers the outer part of the planet. It gives us the many different climates, or broad way of  weather conditions around the world. The hydrosphere includes all of the water on earth from the oceans to glaciers and underground water and it can be liquid, vapour, or ice.

Therefore, the cryosphere the portion of the Earth's surface where water is in solid form for at least one month of the year has been shrinking in response to climate warming.

Answer:

See explanation for detailed solution

Explanation:

The balanced reaction equation is Ba(NO3)2 + 2HSO3NH2 → Ba(SO3NH2)2 + 2HNO3

Number of moles of Ba(NO3)2 = 1.4 g/ 261.337 g/mol = 5.36 × 10^-3 moles

From the reaction equation;

1 mole of Ba(NO3)2 yields 1 mole of Ba(SO3NH2)2

5.36 × 10^-3 moles of Ba(NO3)2 yields 5.36 × 10^-3 moles of Ba(SO3NH2)2

For HSO3NH2

Number of moles = 2.4g/97.10 g/mol =0.0247 moles

2 moles of HSO3NH2 yields 1 mole of Ba(SO3NH2)2

0.0247 moles of HSO3NH2 yields 0.0247 ×1/2 = 0.0137 moles

Hence, Ba(NO3)2 is the limiting reactant

The theoretical yield of Ba(SO3NH2)2 is 5.36 × 10^-3 moles × 329.4986 g/mol = 1.766 g

b)

Number of moles = mass/ molar mass

Molar mass = mass/ number of moles

Molar mass = 1.6925 g/5.36 × 10^-3 moles = 315.76 g

Answer:

Answer:

Explanation:

Answer: chemical change

Explanation:

A physical change occurs when a substance changes phase. For example, boiling pure water (H₂O) is physical change of substance (from liquid to gaseous state).

Answer:

solid has definite shape and volume.

liquid do not have definite shape but have definite volume.

gas do not have definite shape and definite volume.

solid have lowest compressibility out of three, liquid have more compressibility than solid but less than gases. gases have the highest compressibility out of three. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.

Answer:

270.77 g of CO2.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2C4H10 + 13O2 —> 8CO2 + 10H2O

Next, we shall determine the masses of C4H10 and O2 that reacted and the mass of CO2 produced from the balanced equation. This can be obtained as follow:

Molar mass of C4H10 = (12×4) + (10×1)

= 48 + 10 = 58 g/mol

Mass of C4H10 from the balanced equation = 2 × 58 = 116 g

Molar mass of O2 = 2 × 16 = 32 g/mol

Mass of O2 from the balanced equation = 13 × 32 = 416 g

Molar mass of CO2 = 12 + (16×2)

= 12 + 32 = 44 g/mol

Mass of CO2 from the balanced equation = 8 × 44 = 352 g

Summary:

From the balanced equation above,

116 g of C4H10 reacted with 416 g of O2 to produce 352 g of CO2.

Next, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above,

116 g of C4H10 reacted with 416 g of O2.

From the above, we can see that a higher mass of O2 i.e 416 g than what was given i.e 320 g his needed to react completely with 116 g of O2. Therefore, O2 is the limiting reactant and C4H10 is the excess reactant.

Finally, we shall determine the mass of CO2 produced from the reaction.

In this case, we shall use the limiting reactant because it will give the maximum yield of CO2.

The limiting reactant is O2 and the mass of CO2 produced can be obtained as follow:

From the balanced equation above,

416 g of O2 reacted to produce 352 g of CO2.

Therefore, 320 g of O2 will react to produce = (320 × 352)/416 = 270.77 g of CO2.

Thus, 270.77 g of CO2 were obtained from the reaction.

Explanation:

8 valence electrons

There are a total of 22 valence electrons in the Lewis structure for XeF2. The Lewis structure for XeF2 is a bit tougher since you have to take formal charges into account to find the best Lewis structure for the molecule. Remember that Xenon can have more than 8 valence electrons.

Answer:

317.6 mL

Explanation:

Step 1: Write the balanced neutralization equation

MgO + 2 HCl ⇒ MgCl₂ + H₂O

Step 2: Calculate the mass corresponding to 640.0 mg of MgO

The molar mass of MgO is 40.30 g/mol. The moles corresponding to 640.0 mg (0.6400 g) of MgO are:

0.6400 g × (1 mol/40.30 g) = 0.01588 mol

Step 3: Calculate the moles of HCl that react with 0.01588 moles of MgO

The molar ratio of MgO to HCl is 1:2. The moles of HCl are 2/1 × 0.01588 mol = 0.03176 mol

Step 4: Calculate the volume of 0.1000 M HCl that contains 0.03176 moles

0.03176 mol × (1 L/0.1000 mol) = 0.3176 L = 317.6 mL
