Calculate the amount of the first reactant (in the equation) needed if 100 kg of the first product (in the equation) is made.

1) C7H16 + O2 → CO2 + H2O

3) Na2O2 + H2O → NaOH + O2

5) Fe2(SO4)3 + KOH → K2SO4 + Fe(OH)3

7) C6H5COOH + O2 → CO2 + H2O

9) B2O3 + H2O → B(OH)3

11) CaSO4 → CaS + O2

13) NaCl + H2SO4 → Na2SO4 + HCl

15) Bi(NO3)3 + H2S → Bi2S3 + HNO3

17) AgBr + Na2S2O3 → Na3[Ag(S2O3)2] + NaBr

19) NaOH + FeSO4 → Na2SO4 + Fe(OH)2
