2CH3COOH + Zn = (CH3COO)2Zn + H2
2CH3COO(-) + 2H(+) + Zn = 2CH3COO(-) +Zn(2+) + H2
2H(+) + Zn = Zn(2+) + H2
2CH3COOH + Zn(OH)2 = (CH3COO)2Zn + 2H2O
2CH3COO(-) + 2H(+) +Zn(OH)2 = 2CH3COO(-) +Zn(2+) + 2H2O
2H(+) +Zn(OH)2 = Zn(2+) + 2H2O
2CH3COOH + ZnO = (CH3COO)2Zn + H2O
2CH3COO(-) + 2H(+) +ZnO = 2CH3COO(-) +Zn(2+) + H2O
2H(+) +ZnO = Zn(2+) + H2O
2CH3COOH + Na2CO3 = 2CH3COONa + H2O + CO2
2CH3COO(-) + 2H(+) +2Na(+) + CO3(2-) = 2CH3COO(-) + 2Na(+) + H2O + CO2
2H(+) + CO3(2-) = H2O + CO2
1. Cl₂ + H₂ → 2HCl
2. 2HCl + 2Na → 2NaCl + H₂
3. 2H₂ + O₂ → 2H₂O
4. 2Na + 2H₂O → 2NaOH + H₂
1. S + O₂ → SO₂
2. 2SO₂ + O₂ → 2SO₃
3. SO₃ + H₂O → H₂SO₄
4. Ba(OH)₂ + H₂SO₄ → BaSO₄↓ + 2H₂O
Zn+2HCl= ZnCl2+H2
n(ZnCl2) = n(Zn) по условию реакции n(Zn)= 2моль
m=n*M(Ar) Ar(Zn) =65 М=65г/моль
m(Zn) = 2*65= 130г
Ответ: 130г
