Question

In the feaction 2CO(g)-- O2--2CO2(g), what is the ratio of the moles of oxygen used to moles of CO2 produced?
a)2:1
b)1:1
c)1:2
d)2:2

Answer 1

a) 2:1

Answer 2

IT concerns WHAT you're ASKING is it oxygen the ingredient = a) because the oxygen used isn't the O in CO, that's the O2... so if the CO2 produced has a balanced consistent 2 and the O2 has balanced consistent a million. although, it really is O(2), so there is two situations the range of moles interior the molecule 2:2 may nicely be simplified to at least a million:a million or oxygen gas = d) because the coefficients are then a million:2
