Chemical equation: Application for completing products and balancing

Application for completing products and balancing equations of chemical reactions. Example 1 Write and balance the chemical equation for each given chemical reaction. Hydrogen and chlorine react to make HCl. Ethane, C 2 H 6, reacts with oxygen to make carbon dioxide and water. Solution Let us start by simply writing a chemical equation in terms of the formulas of the substances, remembering that both elemental hydrogen and chlorine are diatomic: H2 + Cl2 → HCl There are two hydrogen atoms and two chlorine atoms in the reactants and one of each atom in the product. We can ... On this page of our Chemistry Tutorial, learn how to represent chemical reactions symbolically using formulas, coefficients, and state symbols—and discover how to count atoms to ensure your equations are balanced, reflecting the law of conservation of mass. Managing your way through a Chemistry course can be difficult. Learn what a chemical equation is, how to write it, and what symbols to use to represent the direction, state, and input of energy of a chemical reaction. See examples of chemical equations and ionic equations with spectator ions and net ionic equations.
