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.
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.
transfer of one or more electrons from one reactant to another.
