Question
Chapter 3, Problem 74E
Interpretation Introduction
Interpretation:
The amount of energy released during formation of water from the reaction of hydrogen and oxygen gas is to be stated.
Concept introduction:
The law of conservation of energy states that energy of the reactants before the reaction and energy of the products after the reaction is same only transfer of energy takes place between reactant molecules during a reaction. In case of multistep reactions, each step has its own enthalpy.

- Enthalpy a A 100.-g sample of water is placed in an insulated container and allowed to come to room temperature at 21C. To heat the water sample to 41C, how much heat must you add to it? b Consider the hypothetical reaction,2X(aq)+Y(l)X2Y(aq)being run in an insulated container that contains 100. g of solution. If the temperature of the solution changes from 21C to 31C, how much heat does the chemical reaction produce? How does this answer compare with that in part a?
