Interpretation: The information given in the thermochemical equation is to be discussed.
Concept introduction:
A chemical equation is an equation showing the reactants and products represented as chemical formulas and separated by an arrow.
Thermochemical equations are balanced stoichiometric chemical equations that are accompanied by information about heat change.
Answer to Problem 58A
The information given in the thermochemical equation is how much heat has been absorbed or released during the given reaction.
Explanation of Solution
A positive value of heat changes or ΔH indicates that the given reaction is exothermic, which means heat has been released in the reaction.
A negative value of heat change or ΔH indicates that the given reaction is endothermic, which means heat has been absorbed in the reaction.
