Question

Given the general chemical equation 3A + 2B → C + 5D,

Answer 1

Answer :

(a) The number of moles of D produced can be, 6.67 moles.

(b) The volume of D prepared can be, 24.5 L

Explanation :

The given chemical reaction is:

$3A+2B\rightarrow C+5D$

Part (a) :

From the balanced chemical reaction, we conclude that:

As, 3 moles of A react to give 5 moles of D

So, 4 moles of A react to give $\frac{5}{3}\times 4=6.67$ moles of D

Thus, the number of moles of D produced can be, 6.67 moles.

Part (b) :

As we know that 1 moles of substance occupies 22.4 L volume of gas.

As, $2\times 22.4L$ volume of B gives $5\times 22.4L$ volume of D

As, 9.8 L volume of B gives $\frac{5\times 22.4L}{2\times 22.4L}\times 9.8L=24.5L$ volume of D

Thus, the volume of D prepared can be, 24.5 L
