Question

Закончите уравнение реакций: а)Fe+HCl б) Al+H2So4 в) Ba+HCl г) Zn+H2So4 д)Li+HCl e)Li2O+HCl ж)CaO+H3Po4 з) MgO+HNO3 и) Fe2O3+H2SO4

Answer 1

Fe + 2HCl = FeCl2 + H2↑
2Al +3 H2SO4 = Al2(SO4)3 +3H2↑
Ba + 2HCl = BaCl2 + H2↑
Zn+ H2SO4 = BaSO4↓ + H2↑
2Li + 2HCl = 2LiCl + H2↑
Li2O + 2HCl = 2LiCl + H2O
3CaO +2H3PO4 = Ca3(PO4)2↓ + 3H2O
MgO + 2HNO3 = Mg(NO3)2 + H2O
Fe2O3 + 3H2SO4 = Fe2(SO4)3 + 3H2O

Answer 2

Fe + 2HCl -> FeCl2 + H2
2Al +3 H2SO4 -> Al2(SO4)3 +3 H2
Ba + 2HCl -> BaCl2 + H2
Zn+ H2SO4 -> BaSO4 + H2
2Li + 2HCl -> 2LiCl + H2
Li2O + 2HCl -> 2LiCl + H2O
3 CaO +2 H3PO4 -> Ca3(PO4)2 + 3H2O
MgO + 2HNO3 -> Mg(NO3)2 + H2O
Fe2O3 + 3H2SO4 -> Fe2(SO4)3 + 3H2O
