How does the law of conservation of energy apply to calorimetry?
The conservation of energy is what makes a useful analytical tool for chemical reactions.
It is because we know that energy is conserved that we can use a calorimeter to measure the total heat gained or lost in a chemical reaction. This information is used in thermodynamics to understand how to make a particular reaction work, or if it is not even possible for one to occur.
