When a substance freezes, what happens to the mass? The mass stays constant as it changes from a liquid to a solid.

The mass increases as it changes from a liquid to a solid.

The mass decreases as it changes from a liquid to a solid.

There is no mass once the substance becomes a solid

Answers

Answer 1

Answer: The correct answer is the first statement. The mass stays constant as it changes from a liquid to a solid. According to the Law of Conservation of Mass, mass is conserved. It is not created nor destroyed. Therefore, as the substance turn into solid, all of the substance goes only to the solid phase.

Answer 2

Answer: The mass stays constant as it changes from a liquid to a solid

Atoms gain or lose electrons to increase:a. reactivity
c. stability
b. nucleus size
d. atomic mass

Answers

Atoms gain or lose electrons toincrease their stability. The answer is letter C. Remember noble gases? Theyfollow the octet rule in which their shells are electrons are filled with eightelectrons. So the atoms that do not belong to the noble gas tend to berestless. They want their electrons to be filled to follow the octet rule. Thatis why they tend to share or gain electrons. Suppose you have a compound ofCCl4. You know that chlorine can only share 1 electron because 7 of itselectrons are filled. Also, in carbon, it can only share 4 electrons because 4of it are already filled. That is why carbon needs four chlorine to form CCl4.

Bromine, a liquid at room temperature, has a boiling point of 58° C and a melting point of -7.2° C bromine can be classified as a Compound, impure substance, mixture, or pure substance

Answers

The answer to the chemistry question above would be pure substance. Bromine is classified as a pure substance because only the element is present and there are no other substances added or mixed with it. It is also not a compound because it does not come with another element.

Answer:

pure substance

Which best describes the particles in a gas when the temperature rises from 23 °C to 46 °C? A. The average energy doubles.

B. The average energy increases.

C. The average velocity of the particles increases by a factor of sqrt 2 .

D. The average energy remains constant but the velocity of some particles increases

Answers

I think the correct answer is b. Temperature is proportional to the average kinetic energy so when temperarure rises so will the average kinetic energy. I hope this helps. Let me know if anything is unclear.

Final answer:

When the temperature of a gas rises, the average energy of the particles increases. According to the Kinetic Molecular Theory, kinetic energy is proportional to its temperature. However, a rise in temperature doesn't directly double the energy.

Explanation:

The behavior of particles in a gas is very much affected by temperature changes. When the temperature of a gas increases, so too does the energy that the gas's particles have. This is defined by the Kinetic Molecular Theory, which states that the kinetic energy of a gas is proportional to its temperature. Therefore, when the temperature of a gas rises from 23°C to 46°C, the average energy of the particles increases. However, it doesn't double as an increase in temperature is not responsible for directly doubling the energy. Additionally, this increase in energy results in an increase in the velocity of the particles, but not necessarily by a factor of sqrt(2).
