Answer :
They treated as both reactants and products are represented using formulas. The right reactant and the left reactant are placed adjacent to the reaction arrow.
An expression used to describe a chemical equation is reactant. Reactant are substances that are present at the start of a chemical reaction and change as the reaction proceeds. They could alternatively be called raw ingredients or reagents. Another element that is present at the beginning of a chemical reaction that is either completely or partially consumed to produce the products is known as a reactant. In a chemical equation, the reactants are to the left of the arrow. Reactants in the first equation, for instance, are A and B, while AB and CD are the reactants in the second equation. Reactants are consumed during chemical reactions; reagents are not always consumed. A catalyst is an example of a reagent since it speeds up the reaction while maintaining its stability. Catalysts can be tiny molecules or enormous, complex entities like enzymes.
