Question

Сa-Ca(OH)2-CaCO3-CaO-CaCL2-Ca-Ca3N2-----генетическая связь

Answer 1

1. Ca +  2NaOH=Ca(OH)2 + 2Na

2. Ca(OH)2 + H2CO3 = CaCO3 + 2H2O

3. CaCO3 = CaO + CO2

4.CaO + 2HCl = CaCl2 + H2O

5. CaCl2 = Ca + Cl2 или CaCl2 = Ca + 2Cl

6. 3Ca + N2 = Ca3N2

Answer 2

1) Ca+2H2O=Ca(OH)2+H2

2) Ca(OH)2+CO2=CaCO3+H2O

3)  CaCO3=CaO+CO2

4) CaO+2HCl=CaCl2+H2O

5) CaCl2+2Li=2LiCl+Ca

6) 3Ca+2N=Ca3N2
