The percentage yield of a reaction can best be described as the times 100%. a. amount of desired product divided by the amount of unwanted product b. total amount of materials involved in a reaction c. amount of reactants left over divided by the original amounts d. amount of product you could make if the reaction went to completion e. amount of product obtained divided by the maximum possible amount of product

The correct option is: e. amount of product obtained divided by the maximum possible amount of product

Explanation:

The percent yield of a given chemical reaction is the percentage of the actual yield obtained divided by the theoretical yield.

Here, the actual yield is the amount of the desired product obtained in a given chemical reaction.

Whereas, theoretical yield is the calculated amount of the desired product that can be formed from the given amount of reactants in a given chemical reaction.

The actual yield and the theoretical yield are generally taken in grams.

c.

explanation:

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
