Question

Mrs. Davis has asked Kyle to retrieve the compound mixture from the chemical cabinet. Which of the following should Kyle retrieve?

A) Water

B) Oxygen

C) Chlorine

D) Aluminum

Answer 1

Answer:

water

Explanation:

coz out of the choices water is the only one that is not an element.

water formula is H2O

Answer 2

The water is the only compound in which retrieval is possible in the form of oxygen and hydrogen. Hence, option (A) is correct.

The retrieval of components from the compound mixture is the process of separating each element from the compound, such that the process meets minimum energy waste and cost .

In the given problem, the compounds with chemical formula are:

(A)  Water - Chemical formula is $H_{2}O$.

(B)  Oxygen - Chemical formula is O.

(C) Chlorine - Chemical formula is Cl.

(D) Aluminum - Chemical formula is Al.

Out of the given choices, only water forms a compound mixture of hydrogen and oxygen, whereas other are the pure elements. Oxygen, Chlorine and Aluminum are already in separated state, and from water one can retrieve the oxygen and hydrogen by passing electric current, this process is known as electrolysis.

Thus, we can conclude that the water is the only compound in which retrieval is possible in the form of oxygen and hydrogen. Hence, option (A) is correct.
