Question

What burns to produce one product? What does not change litmus paper (either way)? a. carbon dioxide b. carbon monoxide

Answer 1

Carbon monoxide (`CO`) may be oxidized to `CO_2`.......

Explanation:

And we could represent the reaction by the following reaction:

`a.` `CO(g) + 1/2O_2(g) rarr CO_2(g)`

Carbon dioxide is an acidic oxide...............

`b.` `CO_2(g) + H_2O(l) rightleftharpoonsHCO_3^(-)+H_3O^+`

And such solutions are slightly acidic.

But carbon monoxide does not undergo acid-base reaction in water. In coordination chemistry `""^(-)C-=O^(+)` is often labelled as a `pi-"acid"`, as it is an electron-pair acceptor, as well as an electron pair donor, but this is another story.
