Question

When 2.48g of white phosphorus is heated with 4.8g

Answer 1

Then till second substance

Answer 2

Answer:

P4 + 3NaOH + 3H2O → 3NaH2PO2 + PH3

- According to this reaction:

124 gm of Phosphorous reacts with 120 gm of NaOH to produce 34 gm of PH3.

⇒ 2.48 gm of phosphorous will react with 2.4 gm of NaOH to produce 0.68 gm of PH3

⇒ The theoretical yield = 0.68 gm

- The actual yield = 0.51 gm

- Percentage yield = (Actual yield/Theoretical Yield) × 100

⇒ % yield = (0.51/0.68) × 100

⇒ % yield = 75 %

- So, the percentage yield of the reaction is 75 %.
