Question

Q.6 Combustion of methane is an example of - Exothermic reaction Endothermic reaction ооо Combustion Decomposition reaction.​

Answer 1

Answer:

Combustion reactions

All combustion reactions fall into the pattern:

fuel + O2 ->CO2 + H2O

The coefficients of the balanced equation will change depending on the fuel. The fuel can be almost anything including methane (CH4), propane (C3H8), butane (C4H10), octane (C8H18) or sugar (C6H12O6).

The balanced equation for methane is CH4 + 2 O2 -> CO2 + 2 H2O

Answer 2

in an exothermic reaction , energy released over The course of the reaction

it takes less energy to break bound in the reactants than is required to from bonds in the product. this results in negative enthalpy of reaction.
