<span>A chemical reaction in which compounds break up into simpler constituents is D. decomposition. This should be an obvious answer - when something decomposes, it falls apart and creates smaller parts of the original thing. The same thing goes with the compounds - they will fall apart into constituents that are way simpler than them. </span>
Answer:
Each element has its own unique properties. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. The atomic number of an element is equal to the number of protons that element contains. The mass number is the number of protons plus the number of neutrons of that element. Therefore, it is possible to determine the number of neutrons by subtracting the atomic number from the mass number.

Answer:
<u>-16200J</u>
Explanation:
(257J/g)(62.9g)
eliminate the variables
u get 16165.3
go to 3 significant digits
u get 16200
and since it is freezing we are taking out energy so it would be
-16200J
