Five Factors involved in the construction of a chemical equation.
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.
Precipitation
result in the formation of one or more insoluble products.
Acid-Base reactions
