Answer 1

6.2 Acid-H2SO4-Acid sulfuros 
Baza-Ca(OH)2-Hidroxid de calciu
Oxid bazic-CaO-Oxid de calciu
Oxid acid-CO2-Oxid de cupri (IV)
Sare-CuSO4-Sulfat de cupru

6.3 Ca+O2--->CaO-oxid de calciu
S+O2---->SO3-oxid de sulf 
Ba+O2---->BaO-oxid de bariu

BaO+H2O----->Ba(OH)2-hudroxid de bariu
NaO+H2O---->NaOH-hidroxid de natriu
Ca+H2O--->Ca(OH)2+H2-hidroxid de calciu

SO2+H2O--->H2SO3-acid sulfuric
CO+H2O--->H2CO3-acid carbonic
H2+Cl2--->HCl-acid clorhidric

NaOH+HCl--->NaCl+H2O
BaO+HCl--->BaCl2+H2O
BaO+ZnCl2--->BaCl2+ZnO
ZnO+HCl---->ZnCl2+H2O
