Допишiть рiвняння реакцiй: 1. H2SO4 + Mg= MgSO4+H22. Ba + H2SO4 =3. Na +HCL=4. Са +HCL=5. Cu + HCL =6. Mg+ H3PO4 =7. Zn + H3PO4 =

Answer 1

Ответ:

Ba + H2SO4 = BaSO4 + H2

Na + HCl = NaCl + H2

Ca + HCl = CaCl2 + H2

Cu + HCl = CuCl2 + H2

Mg + H3PO4 = Mg3(PO4)2 + H2

Zn + H3PO4 = Zn3(PO4)2 + H2

Answer 2

1. H2SO4 + Mg = MgSO4 + H2
2. Ba + H2SO4 = BaSO4 + H2
3. Na + HCl = NaCl + H2
4. Ca + 2HCl = CaCl2 + H2
5. Cu + 2HCl = CuCl2 + H2
6. Mg + H3PO4 = Mg3(PO4)2 + H2
7. Zn + 2H3PO4 = Zn3(PO4)2 + 3H2
