The number of moles of H2S released by complete hydrolysis of P2S5with...
P2S5 exits as Dimer.(P4S10)
The dimer of P2S5, known as P4S10, is a compound consisting of four phosphorus atoms and ten sulfur atoms. When it undergoes complete hydrolysis with H2O, it will produce phosphoric acid (H3PO4) and hydrogen sulfide (H2S) according to the balanced chemical equation:
P4S10 + 20H2O → 4H3PO4 + 10H2S
From this equation, we can see that 1 mole of P4S10 produces 10 moles of H2S when it reacts with water. If you want to produce 10 moles of H2S, you would need 1 mole of P4S10.
So, to produce 10 moles of H2S, you would need 1 mole of the dimer P4S10.

The number of moles of H2S released by complete hydrolysis of P2S5with...
To determine the number of moles of H2S released by complete hydrolysis of P2S5 with H2O, we need to understand the reaction that takes place between P2S5 and H2O.
The chemical formula for P2S5 is diphosphorus pentasulfide, and it consists of two phosphorus atoms and five sulfur atoms. When P2S5 reacts with water (H2O), it undergoes hydrolysis to produce phosphoric acid (H3PO4) and hydrogen sulfide gas (H2S).
The balanced equation for the hydrolysis reaction is as follows:
P2S5 + 5H2O → 2H3PO4 + 5H2S
From the balanced equation, we can see that for every one mole of P2S5, five moles of H2S are produced. Therefore, to find the number of moles of H2S released, we need to determine the number of moles of P2S5.
Since the question does not provide the amount of P2S5, we assume we have one mole of P2S5 for simplicity. Hence, according to the balanced equation, one mole of P2S5 would produce five moles of H2S.
Therefore, the correct answer is option 'B' - 10 moles of H2S.
Summary:
- P2S5 reacts with H2O to undergo hydrolysis.
- The balanced equation for the reaction is P2S5 + 5H2O → 2H3PO4 + 5H2S.
- For every one mole of P2S5, five moles of H2S are produced.
- Assuming we have one mole of P2S5, the number of moles of H2S released would be 10.
