If the temperatures of separate 35 g samples of gold, mercury, and carbon are to be raised by 10.0°c. how much heat must be applied to each substance?

The amount of heat applied to each substance is 3.5 g . i did this by calculating 10.0 divided by 35 which gives me the answer 3.5 g. 

What is the question?

Well you can immediately rule out a and d because if a metal were to lose or gain protons, then it would become a different element all together. the answer here is b because the positive symbol with a number refers to how many electrons the metal can give away to become stable.
