X is an ionic compound containing only magnesium, aluminium andoxyge

1.	X is an ionic compound containing only magnesium, aluminium andoxygen. Which of the following can bethe formula of X?a. Mg AIOb. MgAl204c. MgAIOAd. Mg,AIO
Answer» ong>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.

ong>Answer:

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.
