Which carboxylic acid produces a ketone with eight carbon atoms when its calcium salt is heated?

Pentanoic acid (CH₃CH₂CH₂CH₂COOH) forms calcium pentanoate, which decarboxylates to heptan-4-one (CH₃CH₂CH₂COCH₂CH₂CH₃), an eight-carbon ketone.

Which compound evolves CO₂ when its calcium salt is heated with calcium methanoate?

Pentanoic acid (CH₃CH₂CH₂CH₂COOH) forms calcium pentanoate, which, when heated with calcium methanoate ((HCOO)₂Ca), yields pentanal (CH₃CH₂CH₂CH₂CHO) and CO₂.
