Question

Решите и распишите химическую цепочку: H2-HCl-CaCl2-CaCO3-CaO-Ca(OH)2-Ca(NO3)2

Answer 1

H2+CL2-->2HCL
2HCL+Ca(OH)2-->CaCL2+2H2O
CaCL2+H2CO3-->CaCO3+2HCL
CaCO3-->CaO+CO2
CaO+H2O-->Ca(OH)2
Ca(OH)2+HNO3-->Ca(NO3)2+2H2O

Answer 2

H2+Cl2 = 2HCl
CaO + 2HCl = CaCl2 + H2O
CaCl2 + Na2CO3 = CaCO3 + 2NaCl
CaCO3 =t= CaO + CO2
CaO + H2O = Ca(OH)2
Ca(OH)2 + 2HNO3 = Ca(NO3)2 + 2H2O

Ca(OH)2 + Cu(NO3)2 = Ca(NO3)2 + Cu(OH)2
