The balanced chemical equations for the reactions are as follows:
Ni2O5 + BaO = BaNiO3H3PO4 + BaO = Ba3(PO4)2 + H2OH2SO4 + BaO = BaSO4 + H2OHCl + BaO = BaCl2 + H2O
The balanced chemical equations for the reactions are as follows:
Ni2O5 + BaO = BaNiO3
H3PO4 + BaO = Ba3(PO4)2 + H2O
H2SO4 + BaO = BaSO4 + H2O
HCl + BaO = BaCl2 + H2O
