14.A sample of fluorine gas has a density of _____

yarga [219]

Answer:

d = 0.793 g/L

Explanation:

Given data:

Density of fluorine gas = ?

Pressure of gas = 0.554 atm

Temperature of gas = 50 °C (50+273.15K = 323.15 K)

Solution:

Formula:

PM = dRT

M = molar mass of gas

P = pressure

R = general gas constant

T = temperature

d = PM/RT

d = 0.554 atm × 37.99 g/mol / 0.0821 atm.L /mol.K × 323.15 K

d = 21.05 atm.g/mol/26.53 atm.L /mol

d = 0.793 g/L

If a mixture containing 0.50 moles of N2 and 1.8 moles of H2 is allowed to react according to the equation N2 3H2 2NH3 Group of

Lelechka [254]

Answer: hydrogen is the limiting reactant.

Explanation:

We have the equation $\text{N}_{2}+3\text{H}_{2} \longrightarrow 2\text{NH}_{3}$ .

This means that for every mole of nitrogen consumed, 3 moles of hydrogen are consumed.

Considering the nitrogen, the reaction can occur 0.50 times.
Considering the hydrogen, the reaction can occur 1.8/3 = 0.6 times.

Therefore, hydrogen is the limiting reactant.
