Explain why hydrogen chloride is a gas at room temperature

Chemistry
1 answer:
Effectus [21]2 years ago
8 0

The hydrogen chloride is a gas at room temperature due to the presence of weak intermolecular forces.

<h3>What is hydrogen chloride?</h3>

Hydrogen chloride (HCl) is a chemical compound in which polar covalent bond is present between hydrogen atom and chlorine atom.

This bond is not so strong enough to maintain the stability in the liquid phase, else they are weak intermolecular forces and easily gets break through small amount of energy and having low boiling point. That's why HCl is present in gaseous state at room temperature.

Hence due to weak intermolecular force, HCl is present in gaseous state.

In which pair do both atoms have one electron only in an s orbital in their ground states?
lora16 [44]
The answer to this is letter D.

Chromium's electron configuration is <span>1s2 2s2 2p6 3s2 3p6 3d5 4s1, where the last electron is in the s orbital with only 1. As for Li, it is found in the group 1 metals, and it is a fact that all elements under this group has the their last electron to be in the s orbital with only one electron in their outermost shell. 

</span>The electron configuration<span> associated with the lowest energy level of the atom is referred to as </span>ground state and each electron ion is in the lowest energy level possible. When the moment comes that electrons go into a higher level of energy, that is what we call the excited state.

A mole equals 6.02 x 10^23 . Answer these questions below.
siniylev [52]

Answer:

1. 1.25 mol ants x 6.02*10^23 ants/1 mol ants = 7.53*10^23 ants

2. 4.92*10^26 pencils x 1 mol pencils/6.02*10^23 pencils = 817 mol pencils

3. 0.26 mol molecules x 6.02*10^23 molecules/1 mol molecules = 1.6*10^23 molecules

4. 3.46*10^19 molecules x 1 mol molecules/6.02*10^23 molecules = 5.75*10^-5 mol molecules

5. 5.3*10^20 atoms x 1 mol atoms/6.02*10^23 atoms = 8.8 mol atoms

6. 0.11 mol atoms x 6.02*10^23 atoms/1 mol atoms = 6.6*10^22 atoms

I would suggest looking into "dimensional analysis" for help with this type of material. Dimensional analysis will stick with you all throughout chemistry, so picking it up will be extremely beneficial.

A spacecraft is filled with 0.500 atm of N2 and 0.500 atm of O2. Suppose a micrometeor strikes this spacecraft and puts a very s
Archy [21]

Answer:

N2 is lost from the craft 6.9% faster than O2 is lost.

Explanation:

<u>Step 1:</u> Data given

0.500 atm of N2

0.500 atm of 02

Molar mass of 02 = 2*16 g/mole = 32 g/mole

Molar mass of N2 = 2* 14 g/mole = 28g/mole

<u>Step 2:</u> Calculate the rate of loss

r1N2 / r2O2 = √(M2(02)/M1(N2))  = √(32/28) = 1.069

1.069-1)*100= 6.9%

This means N2 is lost from the craft 6.9% faster than O2 is lost.
