What is done to convert a skeletal chemical equation into a balanced chemical equation?
Answer and explanation
Correct answer: Suitable coefficients are used to make the number of atoms of each element equal on both sides
While balancing, the chemical formulae and identities of substances are not changed. Suitable coefficients are placed before formulae so that the number of atoms of every element is equal on the reactant and product sides. For example, \(\mathrm{H_2 + O_2 \rightarrow H_2O}\) becomes \(\mathrm{2H_2 + O_2 \rightarrow 2H_2O}\), giving equal numbers of both H and O atoms.
