Question

Ca-ca(oh)2-caco3-ca(hco3)2-cacl2-agcl

Answer 1

Ca+2H2O=Ca(OH)2+2H2Ca(0)-2e=Ca(+2)2H(+1)+2e=H2Ca(0) восстановительH(+) окислитель
Ca(OH)2+H2CO3=CaCO3+2H2OCa(2+)+2OH(-)+2H(+)+CO3(2-)=CaCO3+H2OCaCO3+2HCL=CaCl2+H2O+CO2CaCL2+2AgNO3=2AgCl+Ca(NO3)2

Answer 2

The chemical equation that represents the reactions occurring between the compounds Ca(OH)2, CaCO3, Ca(HCO3)2, CaCl2, and AgCl is:

Ca(OH)2 + CaCO3 + 2HCl → 2CaCl2 + 2H2O + CO2

Ca(HCO3)2 → CaCO3 + H2O + CO2

AgCl + HCl → AgCl2- + H+

In this reaction, Ca(OH)2 and CaCO3 react with HCl to form CaCl2, water (H2O), and carbon dioxide (CO2). Ca(HCO3)2 decomposes into CaCO3, water, and CO2. Finally, AgCl reacts with HCl to form AgCl2- and H+.
