Hi, so to solve for this, we need to identify the limiting reactant in our reaction.
00:07
We'll calculate the mole ratio since we have the number of moles of the reactants already.
00:13
So mole ratio is the number of moles of the reactant divided by the coefficient of that reactant from the balance equation.
00:19
So if we have al2s3, if we have 32 moles of this reactant, divide the coefficient, which is 1, so we'll still get 32.
00:27
And then for water, h2o, we also have 32 moles, and then the coefficient of water is 6, so we'll get 5 .33.
00:36
And whichever gives the smallest mole ratio will be the limiting reactant.
00:40
So that means h2o is our limiting reactant.
00:44
Why did we have to identify the limiting reactant? because the amount of the limiting reactant will be the basis in the amount of the product that will be formed from the reaction...
