Answer 1

2LI+2H2O=2LIOH+H2

Cu+H20=CuO+H2

Al+H20=2AL(OH)+H2

Mg+2H2O=Mg(OH)2+H2

Ba+2H2O=Ba(OH)2+H2

Ca+H=CaH2

Na+H2SO4(K)=Na2SO4+H2S+H2O

AI+H2S=Al2S3+H2

Ca+H3PO4=Ca3(PO4)2+H2

 2HCI+Zn=ZnCl2+H2 

H2SO4(к) + Cu=CuSO4+SO2+H2O

 H2S+Mg=MgS+H2

HNO3 (K)+Cu=Cu(NO3)2+NO2+H20

Answer 2

1. Li + H2O = LiOH + H2 2. Cu + H2O = CuO + H2 3. Al + H2O = Al(OH)3 + H2 4. Ba + H2O = Ba(OH)2 + H2 5. Mg + H2O = Mg(OH)2 + H2 6. Ca + HCl = CaCl2 + H2 7. Na + H2SO4(K) = Na2SO4 + H2 8. Al + H2S = Al2S3 + H2 9. Ca + H3PO4 = Ca3(PO4)2 + H2 10. HCl + Zn = ZnCl2 + H2 11. H2SO4(к) + Cu = CuSO4 + H2 12. H2S + Mg = MgS + H2 13. HCl + Cu = CuCl2 + H2 14. HNO3(K) + Cu = Cu(NO3)2 + H2O + NO2 15. H3PO4 + Fe = Fe3(PO4)2 + H2 16. HNO3(p) + Na = NaNO3 + H2O + NO2 17. Pb(NO3)2 + Fe = Fe(NO3)2 + Pb
