How many water is obtained when 3 moles of H2 reacts with 1 mole of O2 ?
As we have learnt,
Concept of limiting reagent and excess reagent -
The reactant which gets consumed and thus limits the amount of product formed is called the limiting reagent.
CH4 (g) + 2O2 (g) → CO2 (g) + 2 H2O (g) ;
In this reaction, if 1 mole of methane and 1 mole of oxygen are taken then oxygen would be limiting reagent.
Moles before reaction: 3 1 0
Moles after reaction: 1 0 2
Moles of water obtained = 2
