What is a chemical equation written before balancing called?

Answer and explanation

Correct answer: Skeletal equation

A skeletal equation shows the chemical formulae of reactants and products, but the number of atoms of each element need not be equal on both sides. For example, \(\mathrm{H_2 + O_2 \rightarrow H_2O}\) is a skeletal equation; when balanced, it becomes \(\mathrm{2H_2 + O_2 \rightarrow 2H_2O}\). In a balanced chemical equation, the number of atoms of every element is equal on both sides.
