#### 10 g of hdyrogen and 64 g of oxygen were filled in a steel vessel and exploded. Amount of water produced in this reaction will be: Option 1) 3 mol Option 2) 4 mol Option 3) 1 mol Option 4) 2 mol

As we 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.

- wherein

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.

The reaction occurs as follows

No. of moles of hydrogen=10/2=5

No. of moles of oxygen=

Taking into account the stoichiometry of the reaction we see,

Therefore, O2 is the limiting reagent, as 1 mol of H2 will be leftover in the reaction.

Moles of H2O formed from 1/2 mol O2=1

Mole of H2O formed from 2 mol O2= 4 mol

Option 1)

3 mol

This option is incorrect

Option 2)

4 mol

This option is correct

Option 3)

1 mol

This option is incorrect

Option 4)

2 mol

This option is incorrect
