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%

Draw and label the parts of a helium atom. Include the mass and charge of each subatomic particle.
mihalych1998 [28]

Explanation:

Helium is the second element on the periodic table.

  Information about helium:

  • it belongs to group O on the periodic table
  • it is has an atomic number of 2
  • Helium exists naturally as gas and it is nonreactive.

  To write an atom we use this format:

                                     ₙᵇGˣ

   G is the symbol of the atom

   n is the atomic number  

   b is the mass number

    x is the charge on the atom

Using the periodic table as guide

    Symbol of helium is He

     Atomic number of helium is 2

     mass number of helium is 4

     charge on helium atom is 0

                              ⁴₂He

Every atom contains protons, neutrons and electrons;

   Electrons are negatively charged. For a neutral atom, the number of electrons is the same as that of protons.

   Protons are positively charge particles in an atom. The atomic number is the number of protons in an atom.

   neutrons do not have charges.

 

   Helium has:

        Number of protons = 2

        Number of electrons = 2

        Number of neutrons = 2

Mass of each subatomic particle:

      1 electron = 9.11 x 10⁻³¹kg

      2 electrons = 1.82 x 10⁻³⁰kg  

     Protons and neutrons have the same mass:

           1 proton = 1.67 x 10⁻²⁷kg

           2 protons = 3.34 x 10⁻²⁷kg

           2 neutrons = 3.34 x 10⁻²⁷kg

Liquid does not act that a solid. how is it different from a solid and gas?
Wittaler [7]
Unlike solid matter, where particles are tightly packed and slightly vibrating, or gas, where particles go around everywhere and are extremely loose, a liquid has particles that are loosely packed but are still in slight contact with each other. Hope that's good enough
