I dont know your question but that is true
(E) ionic aluminum fluoride (AlF3)
Is there a picture of the isotope or?- becaue I can’t help if I don’t have a visual.
Answer:

Explanation:
Hello,
In this case, the chemical reaction is:

Thus, we first identify the limiting reactant by computing the yielded moles of water by both of the reactants:

In such a way, since HBr yields less water than cadmium hydroxide, we infer that HBr is the limiting one, therefore, the yielded mass of water are:
