how much heat is released when 32g of water cools from 46°C and freezes

Answers

The amount of heat released when 32g of water cools from 46°C and freezes is 6182.4 J

Heat: This is a form of energy that brings about the sensation of warmth. The S.I unit of heat is Joules (J)

⇒ Formula:

Q = cm(t₂-t₁).................. Equation 1

⇒ Where:

Q = amount of heat releasedc = specific heat capacity of waterm = mass of watert₁ = Initial temperaturet₂ = Final temperature

From the question,

⇒ Given:

m = 32 g = 0.032 kgt₁ = 46 °Ct₂ = 0 °C (Freezing point)c = constant = 4200 J/kg.°C

⇒ Substitute these values into equation 1

Q = 0.032(4200)(0-46)Q = -6182.4 J

Note: The negative sign tells that heat is released and as such can be ignored.

Hence, The amount of heat released is 6182.4 J

Explanation:

When [tex]^1^8F[/tex] undergoes positron emission, the product nucleus is, [tex]^1^8O[/tex].

What is a positron emission?

In positron emission, also called positive beta decay (β+ decay), a proton in the parent nucleus decays into a neutron that remains in the daughter nucleus, and the nucleus emits a neutrino and a positron, which is a positive particle like an ordinary electron in mass but of opposite charge.

When a proton is converted into a neutron then the positron emission takes place as follows.

[tex]^1_1p\;\rightarrow\;^1_0n\;+\;^0_+1e[/tex]

A positron is represented by the symbol. Therefore, when a positron emission occurs then the resultant nuclei atomic number decreases by a unit mass.

The general equation representing positron emission is as follows.

[tex]^M_ZA\;\rightarrow\;^M_Z_-_1 B\;+\;^0_+1e[/tex]

Hence, fluorine-18 decays by positron emission as follows.

[tex]^1^8_9F\;\rightarrow\;^1^8_8n\;+\;^0_+1e[/tex]

Therefore, when [tex]^1^8F[/tex] undergoes positron emission, the product nucleus is, [tex]^1^8O[/tex].

The reaction below is at dynamic equilibrium. Upper N subscript 2 (g) plus 3 upper H subscript 2 (g) double-headed arrow 2 upper N upper H subscript 3 (g). Which statement is true for the equilibrium system? The concentration of NH3 is greater than the concentration of N2. The concentration of NH3 equals the concentration of N2. The rate of the forward reaction equals the rate of the reverse reaction. The rate of the forward reaction is greater than the rate of the reverse reaction.

Answers

For the reaction below at dynamic equilibrium, it is true that the rate of the forward reaction equals the rate of the reverse reaction.

Let's consider the following reaction at equilibrium.

N₂(g) + 3 H₂(g) = 2 NH₃(g)

What is the chemical equilibrium?

Is a state in which the concentrations of reactants and products are constant and the forward reaction rate and constant reaction rate are equal.

What is the equilibrium constant?

The equilibrium constant (K) is the ratio of the concentrations of the products to the concentrations of the reactants, all raised to their stoichiometric coefficients.

Let's consider which statement is true for the equilibrium system.

The concentration of NH₃ is greater than the concentration of N₂. FALSE. There is not enough information to confirm this, we would need to know the value of K.The concentration of NH₃ equals the concentration of N₂. FALSE. There is not enough information to confirm this, we would need to know the value of K.The rate of the forward reaction equals the rate of the reverse reaction. TRUE. This is always true for a reaction at equilibrium.The rate of the forward reaction is greater than the rate of the reverse reaction. FALSE. At equilibrium, both rates are equal.

Answer:

I believe A is the correct answer.

Explanation:

I note that another response includes C. as another correct answer.  It is possible, but it depends on what is meant by "fixed shape."  I interpret "fixed shape" as the collection of the gases forming a fixed shape on their own.  Gases fill the container they are in (be it a flask, room, or a planet, so they have a fixed shape by that definition.  But a primary definition of gases is that that take on the shape of their container, not a shape of their own.

A. is correct because perfect gases have no interactions (AKA the Ideal Gas Laws).  They may have interactions, and often do, but they are weak.  That's why the ideal gas laws are a good first approximation to how gases change volume based on temperature and pressure.

The two ways the cathode ray tube experiment changed scientists'

understanding of the atom was it showing that atoms can be divided into

J.J Thompson was the scientist which performed the cathode ray tube

of it being deflected to the positive electrode.

His observation showed that the atoms contain sub-atomic particles called

electrons which are negatively charged.

An atom's electron configuration ends with 3p4. If another atom has seven more electrons, what would be the continuation of the electron configuration?

Answers

The continuation of the electron configuration would be [tex]3p^6, 4S^2, 3d^3[/tex].

The initial p orbital is partially filled. Hence, it has to be completely filled first in order to obey the orbital filling rule. Lower energy orbitals are first filled before higher energy orbitals.

After filling the p orbital with 2 electrons from the remaining 7 electrons, higher energy orbital 4s and 3d can then be filled.

It was for the welfare of the Armenian societiesD. The Armenians had committed crimes against the state.Reading excerpt that goes with the questionAt the beginning of the 20th century, there were between 2 and 2.5 million Armenians living in the Ottoman Empire, and millions of Armenians also lived beyond the eastern border of the Ottoman Empire, in territory held by Russia. The Turks Anti-Armenian feelings in the Ottoman Empire erupted into mass violence several times in the late 19th and early 20th centuries When the nationalistic Young Turks party came to power in 1908, violence against Armenians became much more common. Because the main goal of the nationalistic Turkish government was to Turkify the empire (to make all the people in the empire follow Turkish culture), policies became less tolerant of non-Turks and Christians over time. In October 1914, the Ottoman Empire entered World War I on the side of Germany and attacked Russia. Since the vilayets where many Armenians lived were near the Russian-Ottoman border, which was now a war front, the Ottoman government and many Turks accused the Armenians of siding with the Russians. The Young Turks began a propaganda campaign portraying Armenians as an internal enemy.Our fellow countrymen, the Armenians, who form one of the racial elements of the Ottoman Empire, having taken up, as a result of foreign instigation for many years past, with a lot of false ideas of a nature to disturb the public order, and because of the fact that they have brought about bloody happenings and have attempted to destroy the peace and security of the Ottoman state, of their fellow countrymen, as well as their own safety and interests, and, moreover, as the Armenian societies have now dared to join themselves to the enemy of their existence, our Government is compelled to adopt extraordinary measures and sacrifices, both for the preservation of the order and security of the country and for the continuation of their existence and for the welfare of the Armenian societies.
