I'm not positive, but I believe it would be one near the Rocky Mountains.
It is important to take note of th temperature in determining the density of a substance because this will set as a basis and will likely be a variable in the experiment because this will also contribute on the effects of the experiment and a basis of how the experiment has turned to be that way.
An increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often.
D is the answer here look
Answer:
May be third one because of the formation of H2(hydrogen)on the product side.
