When aluminum is mixed with iron(III) oxide, iron metal and aluminum oxide are produced along with a large quantity of heat.
Fe2O3(s) + 2 Al(s) 2 Fe(s) + Al2O3(s) + heat
What mole ratio would you use to determine moles Fe if moles Fe2O3 is known?
I JUST WANT THE ANSWER GOSH
To determine the mole ratio between Fe2O3 and Fe, we can use the coefficients in the balanced chemical equation. The balanced equation is:
Fe2O3(s) + 2 Al(s) -> 2 Fe(s) + Al2O3(s)
From the equation, we can see that the ratio between Fe2O3 and Fe is 1:2. This means that for every one mole of Fe2O3, two moles of Fe are produced. Hence, the mole ratio is:
1 mole Fe2O3 : 2 moles Fe
To determine the mole ratio between Fe2O3 and Fe, you would need to examine the balanced chemical equation:
Fe2O3(s) + 2 Al(s) → 2 Fe(s) + Al2O3(s)
From the equation, you can see that the coefficient of Fe2O3 is 1, and the coefficient of Fe is 2. This means that for every 1 mole of Fe2O3, 2 moles of Fe are produced.
Therefore, the mole ratio of Fe to Fe2O3 is 2:1. This implies that for a known number of moles of Fe2O3, you would have twice that number of moles of Fe.
1. You need to find the arrow key(s) and use them. --> is the way to do it.
2. It is better to give a problem with numbers because it makes it easier to explain.
In this case mols Fe will be twice the mols Fe2O3. That's what the coefficients in the balanced equation tells you.
