If the reactants on the left side of a chemical equation are c3h8 + 5o2, the products in a balanced equation could be a) 4co2 + 3h2o b) 3co2 + 4h2o c) 2co2 + 3h2o d) 3co + 4h2o

The balanced chemical equation for the reaction is

This is an example of balancing chemical equations and in this case, this type of reaction is called a combustion reaction.

Most hydrocarbons undergo combustion reaction in the presence of oxygen to produce two main constituent which are

There are several steps of balancing of chemical equations but the first and most important step is to check the entities in the reactant side and the product side, followed by balancing of other elements, ions or charges as the case may require.

Our first priority here is to see that carbon is balanced in both sides of the reaction and we would add 3 to the right hand side (product) to see to that effect.

Second step is to see we balance the hydrogen side on both reactant and product side of the reaction.

By balancing the hydrogen atoms, it also automatically balance the oxygen atoms to.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

Combustion is a type of chemical reaction in which fuel is reacted with oxygen to form carbon dioxide and water.

The balanced chemical reaction will be:
