Chemical equation: Application for completing products and balancing equations

Application for completing products and balancing equations of chemical reactions. 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. 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 ... Balance Chemical Equation - Online BalancerCheck the balance. Now, both sides have 4 H atoms and 2 O atoms. The equation is balanced. Balancing with algebraic method This method uses algebraic equations to find the correct coefficients. Each molecule's coefficient is represented by a variable (like x, y, z), and a series of equations are set up based on the number of each type of atom. Best for: Equations that are more complex and not easily balanced by inspection. Process: Assign variables ...
