Answer:

The chemical reaction releases 23400 kilojoules due to 1.5 kg-reactant.

Step-by-step explanation:

Given the amount of energy released due to reactant consumption, total energy (
Q), measured in kilojoules, is determined by the following expression:


Q = m\cdot L

Where:


m - Mass of reactant, measured in kilograms.


L - Released heat ratio, measured in kilojoules per gram.

Given that
m = 1500\,g and
L = 15.6\,(kJ)/(g), the total energy released by chemical reaction is:


Q =(1500\,g)\cdot \left(15.6\,(kJ)/(g) \right)


Q = 23400\,kJ

The chemical reaction releases 23400 kilojoules due to 1.5 kg-reactant.
