Question

In a single displacement reaction between 4 FeCl3 and 3 O2, what will the charge of oxygen be?

A. -2
B. -3
C. -1/2
D. -1

Answer 1

In the reaction between 4 FeCl3 and 3 O2, the charge of oxygen will be -2, as it commonly forms ions with this charge to complete its valence shell.

Step-by-step explanation:

In the single displacement reaction between 4 FeCl3 and 3 O2, the charge of oxygen will be -2. Oxygen typically forms anions with a -2 charge to attain a full valence shell, following the octet rule. For instance, in the compound Fe2O3, which is produced from the reaction, iron (Fe) has an oxidation state of +3, while oxygen (O) has an oxidation state of -2, which is the usual charge for oxygen in most of its compounds. Therefore, the correct answer is A. -2.
