Question

Hess' Law can be said to be a consequence of the Law of?

constant composition

conservation of energy

conservation of charge

conservation of mass

Answer 1

B. Conservation of Energy

Explanation:

The First Law of Thermodynamics says that matter and energy can neither be gained nor lost in chemical reactions (or any known reactions, for that matter),

Hess's Law of heat energy in chemical reactions is a result of the First Law of Thermodynamics, which involves the conservation of energy.
