I think it is A as solid atoms are close and gases are far away
The most abundant isotope is the isotope with the mass number the closest to the average atomic mass.
Answer:
See explanation below
Explanation:
This reaction is known as Ketone hydrolisis in acid medium. This involves the formation of an hemi cetal, and then, the acetal. This is often used to convert ketones or aldehydes in ethers.
The first step involves the reaction with the acid. The carbonile reacts with the acid and forms an alcohol there. The next step is the reaction of the alcohol, in this case, the methanol to form the hemi cetal. Then in the third step, we repeat the first step, using acid to turn the OH group into a great leaving group such water. Then the water leaves the molecule, leaving the space wide open in the next step for methanol, and the acetal is formed.

Litmus paper turns red in acidic conditions whether its blue or red litmus ,its not NH3 (ammonia) , neither is it barium hydroxide (A) , sodium hydroxide (B) will make it blue or remain blue (depemding on type of paper used ) so it has to be D which is the chemjcal formula for acetic acid , hope this helps !
