Question

Ca+O2=
Li-Li2O-Li2So4=
Fe+CuSo4=
Ba(No3)2+Na2So4=
K+O2=
In-InO-InCl2
Al+Fe2O3
AgNo3+H3Po4=

Answer 1

2Сa + O2 -> 2CaO
4Li + O2 -> 2Li2O
Li2O + H2SO4 -> Li2SO4 + H2O
Fe + CuSO4 -> FeSO4 + Cu
Ba(NO3)2 + Na2SO4 -> BaSO4 + 2NaNO3
4K + O2 -> 2K2O
 2In + O2 -> 2InO
InO + 2HCl -> InCl2 + H2O
2Al + Fe2O3 -> Al2O3 + 2Fe
 3AgNO3 + H3PO4 -> Ag3PO4 + 3HNO3

Answer 2

4li+o2=2li2o
li2o+h2o=2lioh
lioh+h2so4=li2so4+2h2o
