In a molecule of PCl3, 6 electrons will form

Chemistry
1 answer:
Igoryamba3 years ago
8 0

Answer:

polar covalent bonds

Explanation:

Phosphorus trichloride is a chemical compound of phosphorus and chlorine, having the chemical formula PCl 3. It has a trigonal pyramidal shape, owing to the lone pairs of electrons on the phosphorus atom.

Chlorine is more elctronegative than phosphorus . Phosphorus has a lone pair of electrons and every chlorine atom has three pairs of electrons . The molecule is not symmetrical as the shared electron pairs are closer to the chlorine atoms than the phosphorus atoms , the chlorine atoms are shifted towards one side of the center of the molecule , thus a net dipole effect is created. This is the reason why the molecule is polar .

What is the mass of 2N at 0.2829 atm 1.35 L and 25°C
maria [59]
<h3>Answer:</h3>

0.437 g

<h3>Explanation:</h3>

From the question we have;

Pressure of the gas as 0.2829

Volume of the gas as 1.35 L

Temperature of the gas as 25°C

But, K = °C + 273.15

Therefore, temperature of the gas is equivalent to 298.15 K

We are required to calculate the mass of the gas

<h3>Step 1: Number of moles of the gas </h3>

Using the ideal gas equation, PV = nRT , we can determine the number of moles.

R is the ideal gas constant, 0.082057 L.atm/mol.K

Therefore, rearranging the formula;

n = PV ÷ RT

 = (0.2829 atm × 1.35 L) ÷ (0.082057 × 298.15 K)

 = 0.0156 mole

Therefore, the number of moles of the gas is 0.0156 mole

<h3>Step 2: Mass of the gas </h3>

We know that mass of a compound is the product of moles and the molar mass.

Mass = Moles × Molar mass

Molar mass of the gas is 28.0134 g/mol

Therefore;

         = 0.0156 mole × 28.0134 g/mol

         = 0.437 g

Thus, the mass of the gas is 0.437 g

If 23.5 g of ammonia (NH3) is dissolved in 1.0 L of solution, what is the molarity?
Alex

The molarity of the ammonia solution is 1.38 M

<h3>Definition of molarity</h3>

Molarity is defined as the mole of solute per unit litre of the solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>Determination of the mole of NH₃</h3>

•Mass of NH₃ = 23.5 g

•Molar mass of NH₃ = 14 + (3×1) = 17 g/mol

•Mole of NH₃ =?

Mole = mass / molar mass

Mole of NH₃ = 23.5 / 17

Mole of NH₃ = 1.38 mole

<h3>Determination of the molarity </h3>

•Mole of NH₃ = 1.38 mole

•Volume = 1 L

•Molarity of NH₃ =?

Molarity = mole / Volume

Molarity of NH₃ = 1.38 / 1

Molarity of NH₃ = 1.38 M
