Verified answer
2Al + 2NaOH + 6H2O -> 2Na[Al(OH)4] + 3H2Cu + HCl реакция не идёт
2Ba + O2 -> 2BaO
3Mg + 2FeCl3 -> 3MgCl2 + 2Fe
CaO + H2O -> Ca(OH)2
Fe + 2HCl -> FeCl2 + H2
Verified answer
2Al + 2NaOH + 6H2O = 2Na[Al(OH)4] + 3H2↑Cu + HCl ≠
2Ba + O2 = 2BaO
3Mg + 2FeCl3 = 3MgCl2 + 2Fe
CaO + H2O = Ca(OH)2
Fe + 2HCl = FeCl2 + H2↑
