Hi Ayush,
In any chemical reaction, the limiting reagent is the substance which is totally consumed when the chemical reaction is complete.
The balanced chemical equation for the given chemical reaction is represented as
It can be concluded from the balanced chemical equation that 2 moles of hydrogen react with 1 mole of oxygen to produce 2 moles of water i.e., to produce water, 4 g of hydrogen reacts with 32 g of oxygen to form 36 g of water.
Therefore, 3 g of hydrogen reacts with of oxygen i.e., 24 g of oxygen.
Now, 29 grams of oxygen is available. So, hydrogen can very easily get 24 g of it to make water.
So, it is confirmed that hydrogen is acting as the limiting reagent and 5 g of oxygen remains unreacted.
Thus, water is formed only with the available amount of hydrogen.
4 g of hydrogen produces 36 g of water.
Therefore, 3 g of hydrogen producesof water i.e., 3.375 g of water.
Hope, this clears your doubt.
Best wishes!
