Hi there.
00:03
In this question, we are given a balanced equation, and balanced equations are very important because the coefficients in a balanced equation give us the ratio in which the reactants react and the products are formed.
00:17
This is known as the mole ratio.
00:20
So what we see from this equation is that two moles of aluminum will react with three moles of the iron two oxide to produce three moles of iron.
00:35
And one mole of the al203.
00:39
We know it's one because there is no coefficient in front of al203, and when no coefficient is written, it's understood that it's a one.
00:48
Just like in math class, we don't write coefficients of one.
00:51
All right, so this gives us the ratio.
00:54
The reactants react in a two to three ratio, producing products in a three to one ratio.
01:00
All right, so we can use this ratio to help us answer this question.
01:04
We wanna know how to you know, how many moles of iron are produced.
01:08
So that is our question mark.
01:11
How many moles of iron? if 0 .60 moles of aluminum are reacted.
01:19
So we're reacting 0 .60 moles.
01:24
To solve this, we are going to need to use the mole ratio between aluminum and iron...
