Question

Given the following mystery ions, X3+ M2- Q2+ J- Which formula would NOT be correct for an ionic compound? A) Q2M2 B) QJ2 Eliminate C) X2M3 D) XJ3

Answer 1

A ) is the right answer

Answer 2

Answer: The correct answer is option (A).

Step-by-step explanation:

Given mystery ions:
`X^(3+),M^(2-).Q^(2+),J^-`

Positive charged ions will form compounds with negatively charged ions.So compounds possible from these ions are:

1)
`X^(3+)+M^(2-)\rightarrow X_2M_3`

2)
`Q^(2+)+M^(2-)\rightarrow Q_2M_2=Q_1M_1`

(Integer in subscript of the ion will get cancelled by dividing with 2.)

3)
`X^(3+)+J^(-)\rightarrow XJ_3`

4)
`Q^(2+)+J^(-)\rightarrow QJ_2`

All the desired compounds enlisted above are possible to be formed. the from the option given the formula would not be correct for an ionic compound will be
`Q_2M_2` that is option (A).

Hence, the correct answer is option (A).
