Four samples of the same material with identical composition and mass were cut as shown in the diagrams below.

When subjected to the same chemical weathering, which sample will weather at the fastest rate?

1) A
2) B
3) C
4) D

D

Explanation:

Sample D will undergo the fastest rate when subjected to chemical weathering.

What is weathering?

From the given choices, option D will have the largest surface area exposed to chemical actions. It has more surface area compared to the others. The more broken a mass is, the more its surface area is.

Reaction rates are affected by:

The last cube has the highest surface area and will have the fastest rate of weathering.

a chair, a bed, and a toothbrush

explanation:

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
