When entering coefficients to balance equations, recall that just writing the symbol implies "1." Therefore, if a coefficient of "1" is required, choose "blank" for that box. Balance the following reaction. AlCl3 + AgNO3 → AgCl + Al(NO3)3?
In order to balance reactions, we need to remember that the number of each element in the reactant and product side should be equal. This is in accordance with law of mass action. We balance the reaction as follows:
