Given the balanced equation representing a reaction: 2CO(g) + O_2(g) -> 2CO_2(g)2CO(g)+O2(g)2CO2(g). What is the mole ratio of CO(g)CO(g) to CO_2(g)CO2(g) in this reaction?

Is it not 1:11:1...?

Explanation:

We could write...CO(g) +1/2O_2 rarr CO_2(g)CO(g)+12O2CO2(g), instead of ...

2CO(g) +O_2 rarr 2CO_2(g)2CO(g)+O22CO2(g)

In either scenario both mass and charge are balanced, as required for a stoichiometric equation...and this is why teachers go to such great efforts to teach stoichiometry....and we could put in numbers to stress the mass balance of the equation....

underbrace(CO(g) +1/2O_2)_"28 g + 16 g = 44 g" rarr underbrace(CO_2(g))_"44 g"
