Помогите пожалуйста Na→NaOH→NaCl-? Ca→CaO→Ca(OH)2→CaCl2-? Zn→ZnO→ZnCl2→Zn(OH)2→ZnSO4 ?
2Na + 2H2O = 2NaOH + H2↑ NaOH + HCl = NaCl + H2O MgO + Ca = CaO + Mg CaO + H2O = Ca(OH)2 Ca(OH)2 + 2HCl = CaCl2 + 2H2O 2Zn + O2 = 2ZnO ZnO + 2HCl = ZnCl2 + H2O 2NaOH + ZnCl2 = Zn(OH)2↓ + 2NaCl Zn(OH)2 + H2SO4 = ZnSO4 + 2H2O
