Question

CaCO3->CaC2->X1->C2Ag2-> X1->винилацетилен  

Answer 1

 CaCO3->CaC2->X1->C2Ag2-> X1->винилацетилен

 

1) 2 CaCO3 + 5 C = 3 CO2 + 2 CaC2
2)CaC2+2H2O=Ca(OH)2 + C2H2
3)С2H2 + 2[Ag(NH3)2]OH = C2Ag2 + 4NH3 + 2H2O
4)C2Ag2 + (NH4)2S = C2H2 + 2NH3 + Ag2S
5)2C2H2=Сu(+)=C4H4

Answer 2

The chemical reaction you've described involves the conversion of calcium carbonate (CaCO3) to vinylacetylene. However, you mentioned two intermediate compounds, X1 and C2Ag2, without providing any specific information about them. In order to provide a complete explanation, I need more details about the compounds X1 and C2Ag2 and their roles in the reaction.
