Answer:

D

Explanation:

Because of their complementary nature, the oxidation and reduction processes together are referred to as redox reactions. The reactant that brings about the oxidation is called the oxidizing agent, and that reagent is itself reduced by the reducing agent. Examples are, mercury(II) oxide, oxygen, and the copper(II) ion are oxidizing agents, and carbon, hydrazine, and zinc are the reducing agents.

Given the general chemical equation 3A + 2B → C + 5D,
Irina-Kira [14]

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
