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.

When 8.70 kJ of thermal energy is added to 2.50 mol of liquid methanol, it vaporizes. Determine the heat of vaporization in kJ/m
Anni [7]

Answer:

The heat of vaporisation of methanol is "3.48 KJ/Mol"

Explanation:

The amount of heat energy required to convert or transform  1 gram of liquid to vapour is called heat of vaporisation

When 8.7 KJ of heat energy is required to vaporize 2.5 mol of liquid methanol.

Hence, for 1 mol of liquid methanol, amount of heat energy required to evaporate the methanol is =   \frac{8.7}{2.5}KJ

 = 3.48 KJ

So, the heat of vaporization \delta H_{vap} = 3.48KJ/Mol

Therefore, the heat of vaporization of methanol is 3.48KJ/Mol

Four gases were combined in a gas cylinder with these partial pressures: 3.5 atm N2, 2.8 atm O2, 0.25 atm Ar, and 0.15 atm He.
Goryan [66]

Answer:

This can be solved using Dalton's Law of Partial pressures. This law states that the total pressure exerted by a gas mixture is equal to the sum of the partial pressure of each gas in the mixture as if it exist alone in a container. In order to solve, we need the partial pressures of the gases given. Calculations are as follows:

Explanation:

P = 3.00 atm + 2.80 atm + 0.25 atm + 0.15 atm

P = 6.8 atm

3.5 atm = x (6.8 atm)

x = 0.51
