Interpretation: The amount of heat released when
Concept introduction:
Thermochemical equations are balanced stoichiometric chemical equations that are accompanied by information about heat change.
Exothermic reactions are those in which heat is absorbed by the reactants and enthalpy change for the reaction is positive.
Answer to Problem 21LC
The amount of heat released when
Explanation of Solution
The given chemical equation is:
Thus it is given that when 1 mol of ethanol burns, the energy released is
Given the amount of ethanol =
Moles of ethanol are found by dividing the given amount of ethanol by the molecular mass of ethanol.
Moles of ethanol given =
For the burning of
Thus, for the burning of
