Решите цепочки по химии 11, 12 и 13

Answer 1

6Na + N2 = 2Na3N

2Na + 2H2O = 2NaOH + H2

2NaOH + CO2 = Na2CO3 + H2

Na2CO3 + 2HCl = 2NaCl + H2O + CO2

CO2 + CaO = CaCO3

4P + 5O2 = 2P2O5

P2O5 + 3Na2O = 2Na3PO4

P2O5 + 3MgO = Mg3(PO4)2

Mg3(PO4)2 + 3 Ca= Ca3(PO4)2 + 3Mg

Mg + Cl2 = MgCl2

Ba + 2HCl = BaCl2 + H2

BaCl2 + H2SO4 = BaSO4 + 2HCl

2BaCl2 + O2 = 2BaO + 2Cl2

BaO + H2O = Ba(OH)2

Ba(OH)2 + CO2 = BaCO3 + H2O
