A solution of iron(III) chlorate was poured into a lithium phosphate solution. Would you expect a precipitate to form if 354.0 m
Artist 52 [7]

Answer:

K. Yes, because Qsp > Ksp for iron(III) phosphate

Explanation:

Lithium chlorate is very soluble in water, that means has a big ksp.

Iron (III) phosphate has a ksp of 1.3x10⁻²²

Ksp formula of iron (III) phospate is:

FePO₄(s) ⇄ Fe³⁺(aq) + PO³⁻(aq)

Ksp = [Fe³⁺] [PO₄³⁻] = 1.3x10⁻²²

Molar concentration of Fe³⁺ and PO₄³⁻ is:

[Fe³⁺] = 0.340L ₓ (2.52x10⁻⁹mol / L) ÷ (0.354L + 0.520L) = <em>9.8x10⁻¹⁰M</em>

[PO₄³⁻] = 0.520L ₓ (4.65x10⁻¹¹mol / L) ÷ (0.354L + 0.520L) = 2.78<em>x10⁻¹¹M</em>

Replacing in Ksp formula:

Qsp = [9.8x10⁻¹⁰] [2.78x10⁻¹¹M] = 2.72x10⁻²⁰

As Qsp > Kps, the equlibrium will shift to the right decreasing the ions concentrations producing FePO₄(s), <em>a precipitate</em>

<em>The ions decreases its concentration until Q = Kps</em>

<em />

Thus, right answer is:

<em>K. Yes, because Qsp > Ksp for iron(III) phosphate </em>

What is the rate of effusion of methane, CH₄, relative to the rate of effusion of acetylene, C₂H₂?​
just olya [345]

Answer:

1.274.

Explanation:

  • Thomas Graham found that, at a constant  temperature and pressure the rates of effusion  of various gases are inversely proportional to  the square root of their masses.

<em>∨ ∝ 1/√M.</em>

where, ∨ is the rate of diffusion of the gas.

M is the molar mass of the gas.

<em>∨₁/∨₂ = √(M₂/M₁)</em>

∨₁ is the rate of effusion of the methane.

∨₂ is the rate of effusion of acetylene gas.

M₁ is the molar mass of methane (M₁ = 16.0 g/mol).

M₂ is the molar mass of acetylene (M₂ = 26.0 g/mol).

<em>∴ The rate of effusion of methane, CH₄, relative to the rate of effusion of acetylene, C₂H₂ = ∨₁/∨₂ = √(M₂/M₁) </em>= √(26.0 g/mol)/(16.0 g/mol) = <em>1.274.</em>
