Ganezh [65]

Answer : The correct answer for mole ratio of H₂O : H₃PO₄ = 6: 4 .

Mole ratio :

It is defined as mole of one substance to another substance in a balanced reaction . In the balanced reaction , the coefficient written before the substances are taken as moles of that substance.

The given balanced reaction between P₄H₁₀ and H₂O is :

P₄O₁₀ + 6 H₂O → 4 H₃PO₄

Mole of H₂O = 6

Mole of H₃PO₄ = 4

Hence mole ratio of Water : H₃PO₄ = 6 : 4

mrs_skeptik [129]

Answer:

VP as function of time => VP(Ar) > VP(Ne) > VP(He).

Explanation:

Effusion rate of the lighter particles will be higher than the heavier particles. That is, the lighter particles will leave the container faster than the heavier particles. Over time, the vapor pressure of the greater number of heavier particles will be higher than the vapor pressure of the lighter particles.

=> VP as function of time => VP(Ar) > VP(Ne) > VP(He).

Review Graham's Law => Effusion Rate ∝ 1/√formula mass.
