Which substance would be considered a nonrenewable resource? a. fertile soil b. crops c. oil d. trees in a forest e. groundwater?

That would be Oil [OPTION C].

Whereas more crops can be planted; groundwater can be restored by rain; forests can undergo afforestation; unfertile soil can be treated; once the supply of oil has been depleted, it is very difficult to replenish.

Explanation:

The law of multiple proportions states that when two same elements form more than a compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers.

Oxide A

3.50g of sulphur combined with 6.00g of oxygen

Oxygen:Sulphur = 6 : 3.5

Oxide B

2.80g of sulphur combined with 9.55g

Oxygen : Sulphur = 9.55 : 2.8

Therefore:

The ratio of Oxygen to Sulphur in Oxides A and B is:

Ratio of Oxygen=1:2

There is exactly twice in Oxide B as in Oxide A.

This result illustrates the law of multiple proportions.
