In this equation the (s) represents the solid state, and the (aq), which is an abbreviation for aqueous, shows that theionsare hydrated—that is, they have a certain number of water molecules attached to them. As sodium chloride dissolves, four water molecules closely associate with the sod...
H2O = Be + H2O + F must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used to balance one element at a time until both sides are equal and the chemical equation is balanced...
