How many liters of phosphine are produced when 34 L of hydrogen reacts with an excess of phosphorus under STP?

Keith_Richards [23]

Answer:

22.67 L of PH₃

Explanation:

The balanced equation is:

$P_4 (s) + 6H_2(g) \to 4PH_3(g)$

From the equation:

$34 L \times \dfrac{1 \ mol \ of H_2 }{22.4 \ L \ H_2} \times \dfrac{4 \ mol \ of \ PH_3}{6 \ mol \ H_2} \times \dfrac{22.4 \ L \ PH_3}{1 \ mol \ PH_3}$

= 22.67 L of PH₃

The diffusion flux is defined as: a) Mass, per unit surface area, per unit time b) Surface area, per unit time c) Time, per unit

s2008m [1.1K]

Answer:

The correct answer is option a.

Explanation:

Diffusion flux is defined as movement of mas of atoms diffusing through the unit area in per unit time.It measured in ( $kg/m^2 s$ ).

$J=\frac{1}{A}\frac{dM}{dt}$

J = diffusion flux

A = Unit area A through which atoms moves.

M = mass of atoms passes in t interval of time.
