Answer:
i would see you tomorrow we have lunch together
Explanation:
Answer:
D
Explanation:
D states a problem because of the population growing. Regulate means control and d stated that their was a problem and a need to control it. Therefore, d I'd really the only valid answer.
Answer:
(a) 1.
(b) 4.
(c) 3.
(d) 2.
Explanation:
Hello,
(a) In this case, we do no take into account the zero digits before the first nonzero digit which is three, therefore it has one significant figure.
(b) In this case, we consider all the given figures since they are all after the first nonzero digit, therefore it has four significant figures.
(c) In this case, we consider all the given figures since they are all after the first nonzero digit including the decimal place, therefore it has three significant figures.
(d) In this case, we consider all the given figures since they are all after the first nonzero digit, therefore it has two significant figures.
Regards.
Benzaldehyde or C6H5CHO would not undergo the aldol condensation because it does not contain an alpha-hydrogen in its structure. Aldol condensation is a type of reaction that happens between an enolate and an aldehyde or ketone leading to a alkene that has a planar structure. The lack of an alpha-hydrogen would not allow for it to undergo such process since it cannot enolize. Benzaldehyde undergoes a nucleophilic reaction known as Claisen-Schmidt condensation. It has somehow same mechanism of the aldol reaction however, the nucleophilic attack on the carbonyl happens even without the alpha-hydrogen but with an enolate that is from a ketone.
