Question

.Identify the type of reaction from the following equation and define it.
CH₄+2O₂ CO₂+2H₂O+heat

Answer 1

Answer:

it exothermic reaction.

The reaction in which heat is released is endothermic reaction.

Answer 2

Answer:

Explanation:

The reaction -

CH₄+2O₂ CO₂+2H₂O+heat

is an exothermic reaction.

An exothermic reaction is the chemical reaction releasing energy through heat or light. The reaction needs less energy to break the bonds in the reactants and is then released when new bonds are formed in the products. It is opposite of an endothermic reaction and is expressed in the chemical equation as - reactants → products + energy.

Another example of an exothermic reaction includes the combustion, like lighting a candle. To light a candle, an initial input of energy causes the oxygen and the wax react to produce the water, heat and carbon dioxide.
