Question

An oxide of carbon `(X)` reacts with amonia to produce urea and important fertilizer. Which of the following combinations will not yeilds `(X)`.
A. `CO_(3)^(2-)+HCloverset(Delta)to`
B. `CaO+Coverset(Delta)to`
C. `C+Excess O_(2)overset(Delta)to`
D. `HCO_(3)^(-)+HCloverset(Delta)to`

Answer 1

Correct Answer - B
`(X)` is `CO_(2)` because `CO_(2)+NH_(3)` under pressure gives urea, reaction (b) does not produce `CO_(2)`
`CaO+Coverset(Delta)toCaC_(2)+CO`
