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#.......

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.

Answer 2

When exposed to carbon dioxide, litmus paper does not change in any way; carbon monoxide burns to produce a single product.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
