This question wants us to fill in the following table.
00:04
So first we have ammonium bromide, which we know must be made out of the ammonium ion and bromine ion.
00:15
And given that the charges of the ions, only one of them by themselves, will balance each other out.
00:22
We can determine the formula of ammonium bromide to be nh4br.
00:32
This next compound has the formula bas, which we know refers to barium sulfide.
00:46
And it is made out of the barium cation and the sulfur anion, which has a charge of negative 2.
00:58
Next we have iron 2 chloride, and we know that iron 2 has a positive 2 charge, and given that iron 2 has a positive 2 charge, while chlorine, the anion of chlorine only has a negative 1 charge, we know that we need 2 chlorine to balance the charge of the iron cation.
01:28
Next we have a compound with a formula pbf2, which we know refers to lead to fluoride, and we know that the cation of lead 2 has a positive to charge...
