Question
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
