Option B has that double bond between C and O that indicates it propanone or acetone.
Thus, it is the correct option.
When concentrated sulfuric acid, H2SO4(l), is added to water it will form a solution containing hydrogen ions and hydrogen sulfate ions. H2SO4 is a strong acid, but only for the first H+. The remaining HSO4^- is a weak acid. Since it forms an acidic solution, it will change blue litmus to red.
The Moon completes one orbit around the Earth in approximately 27 1/3 days and completes one cycle of its phases in approximately 29 1/2 days.
