You know that each carbon atom can take as much as 4 bonds with other elements. A hydrogen can only take one bond, while an oxygen can take 2. Thus, the chemical formula of H₂CO may be written as H₂C=O which is acetaldehyde. Acetaldehyde is an aldehyde. It has a higher vapor pressure because aldehydes have much stronger bonds than hydrogen bonds in alcohols. Hence, it would need a lot energy, thus higher vapor pressure, to break the bonds of an aldehyde than it would for an alcohol.

c.

Hello,
Due to the fact that an odorless gas was released, the chemical reaction between lithium carbonate and a random acid (for instance hydrochloric acid) turns out into:
It is known that carbonic acid is unstable and it quickly decomposes into water and carbon dioxide which is an odorless gas. In spite of the fact that the 
releases 
it isn't the solid since that gas is odorous.
Best regards.
