Hi there.
00:03
In this question, we are given a sentence describing a decomposition reaction, and we want to write a balanced chemical equation for that.
00:12
So remember when we are writing an equation, we need to write the correct formulas for the reactant or reactants on the left, and the correct formula for the product or products on the right.
00:27
If there's more than one reactant or more than one product, we separate them with a plus sign.
00:32
Okay, so let's go ahead and write the formulas for our reactant and our products.
00:37
We are decomposing ammonium chloride.
00:41
Well, ammonium is a polyatomic ion with the formula nh4.
00:46
And it has a one positive charge.
00:49
The chloride ion is a halogen in group 7a, so it forms an ion with a one negative charge.
00:55
So we just have ammonium chloride.
00:58
We don't need to add any subscripts because the charges positive one and negative one add to zero.
01:04
This is decomposing, produce ammonia.
01:08
Amonia is a molecule.
01:10
It has the formula nh3 and hydrogen chloride...
