Question

How many co2 molecules would be formed from the reaction mixture that produces the greatest amount of products?

Answer 1

I think the question is incomplete. Please see below:

Consider the following reaction: 

2 CH3OH(g) + 3 02(g) ==> 2 CO2(g) + 4H2O(g)

Answer 

There are 2 CO2 molecules would be formed from the reaction mixture that produces the greatest amount of products. 2 molecules of CH3OH and 3 molecules of O2 will yield 2 molecule of CO2 and 4 molecules of H2O.

Answer 2

Answer : 2 molecules of $CO_{2}$ will be formed.

Explanation :

Considering the reaction as

$2CH_{3}OH_{(g)}+3O_{2}_{(g}$ -----> $2CO_{2}_{(g)}+4 H_{2}O_{(g)}$

Here, 2 molecules of methyl-alcohol combines with 3 molecules of oxygen to give 2 molecules of $CO_{2}$ and 4 molecules of $H_{2}O$.

If 1 molecule of methanol is used then only one carbon dioxide molecule will be produced. But as per the given reaction two moles of methanol will produce 2 moles of carbon dioxide molecules.
