Reptile [31]3 years ago
4 0

Answer:

The answer to your question is 1.36 x 10²³ atoms

Explanation:

Data

number of atoms = ?

mass of the sample = 34.2 g

Molecule = Cl₂O₅

Process

1.- Calculate the molar mass of Cl₂O₅

Cl₂O₅ = (35.5 x 2) + (16 x 5) = 71 + 80 = 151 g

2.- Calculate the atoms of Cl₂O₅

                     151 g of Cl₂O₅ ---------------- 6 .023 x 10²³ atoms

                       34.2 g of Cl₂O₅ ------------ x

                          x = (34.2 x 6.023 x 10²³) / 151

                          x = 1.36 x 10²³ atoms

How many moles of gas are present in 1.13 L of gas at 2.09 atm and 291 K?
raketka [301]
<h2><u>Answer:</u></h2>

n = 0.0989 moles

<h2><u>Explanation:</u></h2>

n = PV / RT

P = 2.09atm

V = 1.13L

R = 0.08206

T = 291K

Plug the numbers in the equation.

n = (2.09atm)(1.13L) / (0.08206)(291K)

n = 0.0989 moles

  • No of protons=No of electrons=15
<h3>Mass no:-No of neutrons+No of protons </h3>

\\ \tt\longmapsto 15+16=31

Now

  • It has atomic no 15 hence its Phosphorus(P)

Electronic configuration:-

\\ \tt\longmapsto 1s^22s^22p^63s^23p^3.

  • Valency=3

Chloride formula:-

\\ \tt\longmapsto XCl_3

or.

\\ \tt\longmapsto PCl_3

When the electron cloud of a molecule is easily distorted, the molecule has a high _____________.a. polarity b. polarizability c
katovenus [111]

Answer: Option (b) is the correct answer.

Explanation:

Polarity is defined as the development of partial charges on the atoms of a molecule.

Whereas polarizability is defined as the ability or measure of how readily an electron cloud is able to get distorted. More is the polarizability more will be the electron is distorted in nature.

A dipole moment is defined as the measurement of the separation of two opposite electrical charges.

Thus, we can conclude that when the electron cloud of a molecule is easily distorted, the molecule has a high polarizability.
