Explanation:
Some chemical equations cannot be balanced. Some chemical equations cannot be balanced. For example, (NH4)2 SO4 NH4OH + SO2 cannot be balanced, which is consistent with the failure to observe such a reaction in the laboratory..
The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction.
Anne Marie Helmenstine, Ph. D. A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
