which of the following statements best defines the percentage yield of a reaction? the ratio of measured yield over actual yield the amount of product measured after a reaction the amount of measured yield over calculated yield the maximum amount of product that can be obtained

The amount of measured yield over calculated yield.

Explanation:

The % yield of a reaction = (measured yield / calculated yield) x 100.

false

because it does not have the potential to be entirely used up

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
