If 3.60 moles of SiO2 and 3.60 moles of C react to form SiC accodring to the equation
SiO2 + 3 C -> SiC + 2 CO
how many moles of CO will be produced?
a. 1.20
b.2.40
c.3.60
d.7.20
-Do I have to use SiC in any part of the equation, I am very confused and I think I just need to add the moles. Please help.
we need 3 mol of C for each of SiO2
we do not have them
so
only 3.6/3 = 1.2 mol of SiO2 reacts with 3.6 of C
that has 2.4 mol of O
or 2.4 mol of CO
To determine how many moles of CO will be produced in the reaction, you need to use the stoichiometry of the balanced chemical equation.
The balanced equation is:
SiO2 + 3 C -> SiC + 2 CO
From the balanced equation, you can see that for every 1 mole of SiO2, you need 2 moles of CO. This means that the mole ratio between SiO2 and CO is 1:2.
You have 3.60 moles of SiO2, so to find the moles of CO produced, you can set up an equation using the mole ratio:
(3.60 moles SiO2) x (2 moles CO / 1 mole SiO2) = 7.20 moles CO
Therefore, the correct answer is d. 7.20 moles of CO will be produced.
It's important to use the mole ratio derived from the balanced equation to find the correct answer. Simply adding the moles will not give you the correct result.
