Again, another easy and kinda useless example. Try one with all three having a metal.... what happens if there are less than 3 elements and there is no polyatomic ion? ALEKS wants them ALL split with commas. Ex: NiI2 = Ni2+, I-, H20. or FeBr2 = Fe2+, Br-, H20. Also, H2O goes at the end according to ALEKS, not the front. Wish I could insert a screen shot. ALSO it wants you to write them in order as they appear. polyatomic ions do not go first. ALSO what if there is an element with an unpredictable charge like ZnI2? AAAAALSOOOO the compound name does matter because some say Nickel(II) Bromide or Iron(II) Sulfate. This matters.
First, iodine has a predictable charge of -1. If there are two iodide ions, you know they have a total charge of -2 and this informs you that the Zn has a 2+ charge. Second, if there are less than three elements, at least one of them will have a predictable charge. Third, ALEKS doesn't care where you write the water. I just did the problem (literally, just before writing this comment). I wrote one answer with water first, one with water last, and one with water in the middle. They were all marked correct. Fourth, you don't need to know the name. The formula NiBr_2 tells you just as much information as nickel(II) bromide. Last, as I have said before, you are absolutely welcome to not watch my videos. I'm sure you can find ones that are better suited to your needs :)

Bro why are u so angry
I actually found the video very helpful. Thank you Roxi!@@RoxiHulet
