Balance the Following Reaction: Mg(s) + H2O(g)Mg(OH)2(s) + H2(g)

Balance the following equation by entering the correct coefficients. H3PO4 + KOH K3PO4 + H2O

Balance the following equation by entering the correct coefficients. NaHCO3 --> Na2CO3 + H2O + CO2

balance H2SO4 + NaOH --> H2O + Na2SO4

balance H2SO4 + NaOH --> H2O + Na2SO4 so i know you need 2 Na on each side but then I cant figure out the #'s for O or H

so I don't expect you to answer all of these I just don't understand how they work so if someone could just explain one or two so I can do the rest that would be helpful! Thanks! Use the activity series to predict whether the following reaction will occur...
