Question

The enthalpies of formation need to be multiplied by integers as required by the balanced chemical equation.

Select one:

True

False

Answer 1

Answer is True because

To find the enthalpy change for a given reaction can be calculated by

subtracting the enthalpies of formation of the reactants from the enthalpies of formation of the products
-multiply enthalpies of formation by integers as required by the balanced equation
-elements are not included in the calculation since elements require no change in form
-defined enthalpy of formation of an element in its standard state is zero (reference point for calculating enthalpy changes in reactions
