Question

химия срочно пожалуйста​

Answer 1

1. NaOH+HCl=NaCl+H2O

2KOH+H2SO4=K2SO4+2H2O

Ca(OH)2+H2SO4=CaSO4↓+2H2O

Ca(OH)2+2HCl=CaCl2+H2O

2. 2NaOH+SO3=Na2SO4+H2O

Ca(OH)2+SO3=CaSO4↓+H2O

3. 2NaOH+CuSO4=Na2SO4+Cu(OH)2↓

2NaOH+ZnCl2=2NaCl+Zn(OH)2↓

Na2SO4+Ba(OH)2=2NaOH+BaSO4↓

Ca(OH)2+K2CO3=CaCO3↓+2KOH

4. 2Fe(OH)3=3H2O+Fe2O3

Fe(OH)2=H2O+FeO

2Al(OH)3=3H2O+Al2O3
