Answer:
Explanation:
Molar ratio is defined as the ratio of number of moles of reactants or products in a balanced chemical equation.
In this balanced equation, the number of C6H6 molecules react to form 12 CO2 molecules.
Thus, the molar ratio between C6H6 to carbon will be equal to 2 moles of C6H6 divided by 12 moles of CO2
The building of all the profiles is correct; The total number of electrons is correct, as well as the filling of the shells to their entirety. However, some charge calculations are off. First, we see that sodium loses an electron in its structure. Hence, it acquires a charge of +1, not -1. Also, Fluorine gains 2 electrons in its 2p subshell. Thus, its charge is -2, not -1 and this is wrong too. The only correct answer is C; aluminum lose 3 electrons from its p-shell and hence it has a charge of +3.
