Hey there!
The more energy a substance is, the more movement it has.
The energy of a substance determines its state of matter.
From least to most energy, it goes solid, liquid, gas.
So it needs to be going from a lower energy state to a higher energy state.
The only one that goes from a lower energy state to a higher energy state is C. H2O (l) --> H2O (g).
Hope this helps!

Answer:
D. Metals
Out of the 118 elements only about 30% are not made of metal. This can be tested easily if you have household items that have metal in them or some that do not. Additionally you will need a magnet to tell if there is really metal.
Answer:
2HNO3+Ca(OH)2 = Ca(NO3)2+2H2O
Explanation:
The reaction between Nitric acid(HNO3)and Calcium hydroxide(Ca(OH)2) gives Calcium Nitrate( Ca(NO3)2 and Water( H2O)
