• 1. The chemical formulas of the reactants are the reactants are written on the left and those of the products are written on the right.
• 2. A reaction arrow indicating the direction in which the reaction proceeds separates the reactants from the product.
• 3. The physical states of reactants and products are often but not always shown in the parenthesis just after the formula of each.
• 4. The symbol A over the reaction arrow means that energy is neccessary for the reaction to occur.
• 5. The equation will be balanced.

result in the formation of one or more insoluble products.

Involve the transfer of a hydrogen ion, H+, from reactant ( the acid) to the other ( the base). a subtype of double replacement reactions.
