Answer:

Kc = 0.042

Explanation:

PCl₅ → PCl₃ + Cl₂

The equilibrium constant's equation will be

Kc = [PCl₃] [Cl₂] / [PCl₅]

Kc = (0.02 x 0.02) / 0.0095

Kc = 0.0421

The equilibrium constant for the given reaction is 0.0421.

Name three important qualities of water.
Paraphin [41]

Answer:

Water (H

2O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound[18] and is described as the "universal solvent"[19] and the "solvent of life."[20] It is the most abundant substance on the surface of Earth[21] and the only common substance to exist as a solid, liquid, and gas on Earth's surface.[22] It is also the third most abundant molecule in the universe (behind molecular hydrogen and carbon monoxide).[21]

The percentage yield is 72.8 %.

<em>Step 1</em>. Calculate the <em>mass of Br₂</em>

Mass of Br₂ = 20.0 mL Br₂ × (3.10 g Br₂/1 mL Br₂) = 62.00 g Br₂

<em>Step 2</em>. Calculate the <em>theoretical yield</em>

M_r:           159.81    266.69

         2Al + 3Br₂ → 2AlBr₃

Moles of Br₂ = 62.00 g Br₂ × (1 mol Br₂/(159.81 g Br₂) = 0.3880 mol Br₂

Moles of AlBr₃ = 0.3880 mol Br₂ × (2 mol AlBr₃/(3 mol Br₂) =  0.2586 mol AlBr₃

Theor. yield of AlBr₃ = 0.2586 mol AlBr₃ × 266.99 g AlBr₃)/(1 mol AlBr₃)

= 69.05 g AlCl₃

<em>Step 3</em>. Calculate the <em>percentage yield </em>

% yield = (actual yield/theoretical yield) × 100 % = (50.3 g/69.05 g) × 100 %

= 72.8 %
