Given the balanced equation representing a reaction: #2CO(g) + O_2(g) -> 2CO_2(g)#. What is the mole ratio of #CO(g)# to #CO_2(g)# in this reaction?
Is it not
We could write...
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....
