X is an ionic compound containingonly magnesium, aluminium andoxygen.

1.	X is an ionic compound containingonly magnesium, aluminium andoxygen. Which of the following can bethe formula of X?a. Mg AIOb. MgAl204c. MgAIOAd. Mg,AIO
Answer» ANSWER: b. MgAl204 Explanation: Net charge on an ionic COMPOUND is ALWAYS zero. Mg has a charge of 2+, AL has 3+ and O has 2- Let's look at the options and calculate the net charge. Among the given options, MgAl2O4 is the BEST answer. Because its net charge is 0 -> (1)(+2) + 2(+3) + 4(-2) = 0.

Explanation:

Net charge on an ionic COMPOUND is ALWAYS zero.

Mg has a charge of 2+, AL has 3+ and O has 2-

Let's look at the options and calculate the net charge. Among the given options, MgAl2O4 is the BEST answer.

Because its net charge is 0 -> (1)(+2) + 2(+3) + 4(-2) = 0.
