Phosphorous trichloride (PCl3) is produced

Chemistry
1 answer:
vladimir1956 [14]2 years ago
4 0

The percentage yield obtained from the given reaction above is 74.8%

<h3>Balanced equation </h3>

P₄ + 6Cl₂ → 4PCl₃

Molar mass of P₄ = 31 × 4 = 124 g/mol

Mass of P₄ from the balanced equation = 1 × 124 = 124 g

Molar mass of PCl₃ = 31 + (35.5×3) = 137.5 g/mol

Mass of PCl₃ from the balanced equation = 4 × 137.5 = 550 g

<h3>SUMMARY</h3>

From the balanced equation above,

124 g of P₄ reacted to produce 550 g of PCl₃

<h3>How to determine the theoretical yield </h3>

From the balanced equation above,

124 g of P₄ reacted to produce 550 g of PCl₃

Therefore,

79.12 g of P₄ will react to produce = (79.12  × 550) / 124 = 350.9 g of PCl₃

<h3>How to determine the percentage yield </h3>
  • Actual yield of PCl₃ = 262.6 g
  • Theoretical yield of PCl₃ = 350.9 g
  • Percentage yield =?

Percentage yield = (Actual /Theoretical) × 100

Percentage yield = (262.6 / 350.9) × 100

Percentage yield = 74.8%

A reaction at −8.0°C evolves 854.mmol of boron trifluoride gas. Calculate the volume of boron trifluoride gas that is collected.
Bas_tet [7]

Answer:  The volume of boron trifluoride gas that is collected is 18.6 L

Explanation:

According to the ideal gas equation:

PV=nRT

P = Pressure of the gas = 1 atm

V= Volume of the gas= ?

T= Temperature of the gas in kelvin =-8.0^0C=273+(-8.0)=265K

R= Gas constant = 0.0821Latm/Kmol

n=  moles of gas=  854 mmol = 0.854 mol   (1mmol=0.001mol)

1atm\times V=0.854\times 0.0821\times 265

V=18.6L

Thus volume of boron trifluoride gas that is collected is 18.6 L

Blackboard chalk contains a certain percentage of calcium carbonate. If a 1.51 g piece of chalk produces 0.665 g of carbon dioxi
Lapatulllka [165]

The percentage of Calcium carbonate in chalk = 100%

<h3>Further explanation</h3>

Given

1.51 g piece of chalk produces 0.665 g of carbon dioxide

Required

percentage of calcium carbonate

Solution

Reaction

CaCO3 (s) + 2 HCl (aq) → CaCl2 (aq) + H2O (l) + CO2 (g)

mol CO2 :

= 0.665 g : 44 g/mol

= 0.015

From the equation, mol CaCO3 = mol CO2 = 0.015

mass CaCO3 :

= mol x MW

= 0.015 x 100

= 1.5 g
