Question

NaOH+SO2-? FeO+HCI-?
BaO+HCI-? Ca(OH)2+HNO3-?
NaOH+ZNO-? BaCI2+H2SO4-?
FeSO4+NaOH-?
CuCI2+NaOH-?
NaOH+SiO2-?
Al(OH)3+HCI-?

Answer 1

2NaOH + SO2 = Na2SO3 + H2O
BaO+2HCI =BaCl2+H2O
NaOH+ZNO=что токое Z???
FeSO4+2NaOH=Fe(OH)2+Na2SO4
CuCI2+2NaOH=Cu(OH)2+2NaCl
2NaOH+SiO2=Na2O+H2SiO3
Al(OH)3+3HCI=AlCl3+3H2O
FeO+2HCI=FeCl2+H2O
Ca(OH)2+2HNO3=Ca(NO3)2+2H2O
BaCI2+H2SO4=BaSO4+2HCl
