Simple question about limiting reagents in chemistry?
How do I know what molar ratio to use when calculating for limiting reactant? For this one, for example:
CH4 + 2O2 --> 2H2O + CO2
And they want to know how many moles of CH4 and how many moles of O2 reacted...
I always get mixed up at the ratio. For O2, would the ratio be moles2O2:molesCO2 (so, 2:1) or would it be moles 2O2:2H2O (so, 2:2).
Which one and why please?
