Final answer:
The correct ion pair that forms a neutral ionic compound is d. Fe³⁺, O²⁻, resulting in the ionic compound Fe₂O₃, also known as ferric oxide.
Step-by-step explanation:
The student's schoolwork question pertains to identifying the correct ion pair and the resulting ionic compound they form. Looking at the options provided:
-
The correct response to the schoolwork question is d. Fe³⁺, O²⁻; Fe₂O₃, because to form a neutral ionic compound, the total positive charge must equal the total negative charge. Iron (III) ion (Fe³⁺) combining with oxide ion (O²⁻) results in ferric oxide, with the formula Fe₂O₃, where two iron ions each with a charge of +3 balance the charge of three oxide ions each with a charge of -2.
