Question

Write down a general expression for Endothermic & exothermic reaction representing heat​

Answer 1

ANSWER

Some common examples of exothermic reactions that are vital to the everyday lives of human beings are listed below.

Combustion

Commonly referred to as burning, combustion is an exothermic reaction in which a fuel undergoes reduction when exposed to an oxidizing agent (which is usually the oxygen present in the atmosphere) and forms an oxidized product.

These reactions give out good amounts of energy in the form of heat, but also form some byproducts such as smoke.

An example of a combustion reaction would be the combustion of methane which can be represented as follows: CH4 + O2 → CO2 + H2O + Heat

Another example of a combustion reaction is the combustion of glucose, given by the following reaction: C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy
