Ответ:
-43934.8KJ
Explanation:
From the balanced reaction equation:
122g of nitromethane releases -1418000J of heat
3780g of nitromethane will release 3780 × -1418000/122
=-43934.8KJ
The balanced reaction equation must first be obtained before any calculation since the calculation is based on the stoichiometry of the reaction. The mass in kilogrammes must first be converted to grams and the energy expressed in joules before calculations begin.

Hydrolysis reaction
Explanation:
Hydrolysis reaction -
It is the type of reaction , where water is used to bifurcate the bond of some specific compound , is referred to as the hydrolysis reaction.
The reaction of hydrolysis is exactly opposite of the condensation reaction , in which two or molecules combine to form one unit.
Hence, even in case of biomolecules , water is used to break down the molecule into smaller unit , hence , it is type of hydrolysis reaction.
