Which of the following is a possible type of formula for ?
A. Molecular
B. Empirical
C. Inorganic
D. Both A and B
A
The formula cannot be empirical because the ratio of the subscripts is not in lowest form. (An empirical formula for this expression would be ) Thus, choices B and D are eliminated. Inorganic compounds are those that do not contain carbon. Therefore, the only possible answer is A.
