Why does changing the volume of a container change the pressure of the gas in it?

klio [65]

Changing the volume increases the area that the molecules collide with so the force is spread over a larger area.

A sample of chlorine gas has a density of g\L At a pressure of 1.04 for ATM and a temperature of 34°C. Assume Ideal behavior

madam [21]

Answer:

2.93 g/L

Explanation:

We can use the Ideal Gas Law to calculate the density of chlorine.

pV = nRT

n = m/M Substitute for n

pV = (m/M)RT Multiply both sides by M

pVM = mRT Divide both sides by V

pM = (m/V) RT

ρ = m/V Substitute for m/V

pM = ρRT Divide each side by RT

ρ = (pM)/(RT)

===============

p = 1.04 atm

M = 70.91 g/mol

R = 0.082 06 L·atm·K⁻¹mol⁻¹

T = 34 °C = 307.15 K Solve for ρ

===============

ρ = (1.04 × 70.91)/(0.082 06 × 307.15)

ρ = 73.74/25.20

ρ = 2.93 g/L

Two compounds containing six carbon atoms on treatment with either with BH₃ in THF followed by H₂O₂ /OH⁻ (OR) with H₂O / Hg²⁺ / H₃O⁺ gives the same products.
The two alkynes, their two different types of reactons and products are given below,
