Answer In order to balance a chemical equation, the quantities of each type of element and polyatomic ion that are present in the reactants and the products of the reaction must be determined. No polyatomic ions are present in any of the formulas that are shown above.

This equation is not balanced because there are two oxygen atoms on the left side and only one on the right. Assigning a coefficient of 2 to both H 2 O and H 2 gives the balanced chemical equation: \[ 2 H_2 (g) + O_2 (g) \rightarrow 2 H_2O (g) onumber \] Thus 2 mol of H 2 react with 1 mol of O 2 to produce 2 mol of H 2 O. 1. C 2H 6 + O 2 → 3H 2O + 2CO 2. This results in seven O atoms on the product side of the equation, an odd number—no integer coefficient can be used with the O 2 reactant to yield an odd number, so a fractional coefficient, 7 2, is used instead to yield a provisional balanced equation: C 2H 6 + 7 2O 2 → 3H 2O + 2CO 2.Balancing a chemical equation refers to establishing the mathematical relationship between the quantity of reactants and products. The quantities are expressed as grams or moles. It takes practice to be able to write balanced equations. There are essentially three steps to the process: 1. Write the unbalanced equation. Chemical formulas of ... Ionic chemical equations indicate the net electrical charge on reactants and products. In a balanced ionic equation, the net electrical charge is the same on both sides of the reaction arrow. Example: 2Ag + (aq) + Cr 2 O 7 2− (aq) → Ag 2 Cr 2 O 7 (s). Note that you multiply the coefficient by the charge.When a chemical reaction occurs, there is a characteristic change in enthalpy.
