When it comes to chemical equations, it becomes important to first balance your chemical equation because this will later on lead us to our understanding of stoichiometry. Now, stoichiometry deals with the numerical relationship between compounds. In a balanced chemical equation, it allows us to determine the amount of products from reactants and vice versa.
For example, here we have our chemical equation that's balanced. We have two hydrogen gases reacting with one oxygen gas to produce 2 water molecules as gas. They're giving us 12.3 grams of H2, and they're asking us to determine the grams of H2O gas produced. This is what stoichiometry is. They're giving us a balanced chemical equation. They're giving us information on one of the compounds within this balanced equation and asking us to find another compound within that same balanced equation.
Now that we know what stoichiometry is, how exactly do we do it? Well, if you click on the next video, we'll take a look at the procedures that you'll need to employ in order to do any type of stoichiometric calculation.
