00:02 Hi there.

00:03 In this question, we are trying to write the formula for ionic compounds.

00:07 So let's talk for just a moment about ionic compounds.

00:12 Ionic compounds are composed from a cation, which is positive, and an anion, which is a negative ion.

00:26 Ionic compounds also are neutral.

00:31 So that means when writing the formula, we need to make sure that the total positive and negative charges add to zero.

00:50 Okay, so let's look at what we're given here.

00:54 We are given two cations.

00:57 These are the positive ones.

00:59 That would be iron two.

01:02 So it's f .e with a two plus charge.

01:05 And the polyatomic ion, ammonium, which is nh4 with a single positive charge.

01:13 We are also given two anions.

01:17 These are both polyatomic ions.

01:19 We are given cl 03 with a single negative charge and oh minus hydroxide with a single negative charge.

01:29 Okay, and we want to write four formulas.

01:34 Well, we can put iron with each of the negative ions.

01:39 So let's go ahead and do that.

01:41 So we have f .e with its 2 plus charge...
