Question

what is the correct formula that would result from the combination of the two ionic species?
al+3 and co3-2
alco3
al3(co3)3
al2(co3)3
al3(co3)2

Explanation:

Step1: Determine the charge balance

The charge of \(Al^{+3}\) is \(+3\) and the charge of \(CO_3^{-2}\) is \(-2\). To balance the charges, find the least common multiple of \(3\) and \(2\), which is \(6\).

Step2: Calculate the number of ions

For \(Al^{+3}\): \(\frac{6}{3}=2\) ions. For \(CO_3^{-2}\): \(\frac{6}{2}=3\) ions.

Answer:

\(Al_2(CO_3)_3\)
