Question

List 20 balanced chemical equations.

Answer 1

Balanced chemical equations:

• A balanced equation is known as 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.
