Verified by Experts


`CaCO_(3(s)) overset(Delta)(rarr)underset((A))(CaO_((s)))+underset((B))(CO_(2)) uarr_((g))`
`CaO + 3 C rarr underset ((C )) (CaC_2) + underset ((B)) (CO)`
`underset((C))(CaC_(2)) +2H_(2)O rar runderset((F))(Ca(OH)_(2))+ underset((E))(C_(2)H_(2))`
Hence (A) is calucium osiede , `CaO`
(B) is carbon disoxede , `CO_2` .
(C) is calcium carbide, `CaC_2`
(D) is carbnon monoxide, `CO`.
(E) is acetylene `C_2 H_2` .
(F) is calcium hydroxide , `Ca(OH)_2`.
