how come you didn't write the charges for the first two columns? (CH3)2CO and CH3CN

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?

the compound name does matter because some say Nickel(II) Bromide or Iron(II) Sulfate. This matters.
