Answer:

Molarity HNO₃ Soln = 0.625M

Explanation:

Molarity of Acid Soln X Volume Acid Soln = Molarity of Base Soln x Volume of Base Soln

Molarity HNO₃ Soln x 200-ml HNO₃ Soln = 0.50M KOH Soln x 250-ml KOH Soln

Molarity HNO₃ Soln = (0.50M)(250ml)/(200ml) = 0.625M

Answer:

The answer to your question is: C. The specific latent heat of fusion

Explanation:

A. The specific latent heat of vaporization  Specific latent heat of vaporization indicates the transition from liquid to vapor, but we are not looking for this definition. This answer is wrong.

B. The specific heat indicates the amount of heat needed to increase the temperature of water 1°C, so this answer is wrong.

C. The specific latent heat of fusion . This heat indicate the transition from solid ie to liquid, so this is the right answer.

D. The internal energy measures the energy of the molecules of a substance, so this answer is wrong.
