How do would you balance these equations?

CuSO4*5H2O ---> CuSO4 + H2O

C8H18 + O2 ---> CO2 + H2O

P2O5 + H2O ---> H3PO4

HN3 + Zn ---> Zn(NO3)2 + NO2 + H2O

CuSO4*5(H2O) ---> CuSO4 + 5(H2O)

2(C8H18) + 25O2 ---> 16(CO2) + 18(H2O)

P2O5 + 3(H2O) ---> 2(H3PO4)

The last one doesn't balance because there is oxygen on the right side but none on the left.

1. CuSo^5 H2O----> 5CuSo4+ h2o
2. C8h18 + 8O2 -----> 8Co2+ 18H20 not sure bout oxygen i think i'm off by a lil
3. 8p2o5+ 15h2o ---> 10H3po4 hopefully thats right and i'm too tired to do the 4th one good luck
