Ca-CaO-CaCl2-CaCO3-CaO-Ca(OH)2

Question

Ca-CaO-CaCl2-CaCO3-CaO-Ca(OH)2

Answer 1

2Ca+O2=2CaO
CaO+2HCl=CaCl2+2H2O

Comments

CaCl2+Li2CO3=2LiCl+CaCO3

---

CaCO3=CaO+CO2

---

CaO+Mg(OH)2=MgO+ Ca(OH)2

Answer 2

1) 2Ca+O2=2CaO
2) CaO+2HCl=CaCl2+H2O
3) CaCl2+Na2CO3=CaCO3(осадок)+2NaCl
4) CaCO3=t=CaO+CO2
5) CaO+H2O=Ca(OH)2
