Answer:

B.

Explanation:

Elemental analysis involves the actual percentage compositions of each element in the sample of the compounds. We know that there are two different compounds here that both contain copper and oxygen. What we don't know is the actual number of copper or oxygen composed in the compounds.

An elemental composition of these compounds would thus tell us this and will give an idea of the chemical formula of each since we now know quite well the percentage composition of each of these elements

uranmaximum [27]

Temka [501]
The independent variable would be the amount of sunlight because that is what you are testing and the dependent variable would be the length of time the mice slept because it is what you are measuring. The constants would be everything else water, food, cage size, exercise wheel, and temperature because they stay the same.
