Object A at 40
degrees C and object B at 80 degrees C are placed in contact with each other.
The heat flow will flow from the Object B to the object A because of temperature
difference. To attain equilibrium, the heat flow must flow form a higher
temperature to a lower temperature.
Answer:
0.425 moles of P₂O₅.
Explanation:
As per given balanced equation, four moles of phosphorus reacts with five moles of oxygen to give two moles of P₂O₅.
As given that the initial moles of phosphorus taken = 0.97 moles
moles of phosphorus left after reaction = 0.12 moles
moles of phosphorus reacted = 0.97-0.12 = 0.85 moles
When four moles of P reacts they give two moles of P₂O₅.
when one mole of P will react to give =
0.85 moles of P will react to give = P₂O₅
