Answer : The number of moles of formaldehyde produced will be, 4 moles.
Explanation :
Moles of = 4.0 mole
Moles of = 4.0 mole
First we have to calculate the limiting and excess reagent.
The balanced chemical reaction will be :
From the balanced reaction we conclude that
As, 2 moles of react with 1 mole of
So, 4 moles of react with moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Now we have to calculate the moles of .
As, 2 moles of react to give 2 moles of
So, 4 moles of react to give 4 moles of
Therefore, the number of moles of formaldehyde produced will be, 4 moles.
