chatgtp and meta AI said it's A( pouring detergents) other CBT apps like
green bridge , Nigeriascholars, my exam point, and school Ngr. said
pouring detergents
The answer is A
Other options:
Passing ships ❌ makes pollution worse.
Organic solvents ❌ can cause more pollution.
Evaporation ❌ is too slow and incomplete.
B is currect answer here. however, in environmental chemistry, the best method is the use of chemical herder or shell herder. The oil molecules will stick on the sides of the passing ships getting the area rid of oil spill and therefore leading to environmental recovery and remediation. this method is eco- friendly. using detergents will add benzene compounds into the water body causing more pollution. note detergent is alky benzene sulphonate.
A. Pouring detergents ✅
Explanation:
Petroleum spillage on water (oil spill) forms a film that prevents oxygen exchange and is harmful to aquatic life. To disperse the oil, detergents (dispersants) are used because they break down the oil into tiny droplets that mix with water, making it less harmful and easier for microorganisms to degrade.
B. Passing of ships → only stirs the oil, does not disperse it.
C. Pouring organic solvents → dangerous, toxic, and impractical.
D. Evaporation → only removes volatile components, not the bulk of the oil.
please I am confused right now.
my school experts and admins please what is the correct answer to this question 🙏
The correct answer is: A) pouring detergents
Explanation:
Petroleum spillage creates an oil layer on water surfaces, which is harmful to aquatic life. To disperse this oil:
Detergents (or dispersants) break the oil into smaller droplets, allowing it to mix with water and be broken down more easily by microorganisms.
Other options:
B) Passing ships — does little to disperse oil effectively
C) Organic solvents — harmful and expensive, not ideal
D) Evaporation — too slow and incomplete for effective cleanup
Correct and most effective method:
A) pouring detergents
my school came to other year and said pouring detergents while confusing us
