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.

Sodium sulfate dissolves as follows: Na2SO4(s) → 2Na+(aq) + SO42- (aq). How many moles of Na2SO4 are required to make 1.0 L of s

maxonik [38]

<u>Answer:</u> The number of moles of $Na_2SO_4$ is 0.05 moles.

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}$

We are given:

Molarity of solution = 0.10 mol/L

Volume of solution = 1 L

Putting values in above equation, we get:

$0.10mol/L=\frac{\text{Moles of sodium}}{1.0L}\\\\\text{Moles of sodium}=0.10mol$

The chemical reaction for the ionization of sodium sulfate follows the equation:

$Na_2SO_4(s)\rightarrow 2Na^+(aq.)+SO_4^{2-}(aq.)$

By Stoichiometry of the reaction:

2 moles of sodium ions are produced by 1 mole of sodium sulfate

So, 0.10 moles of sodium ions will be produced by = $\frac{1}{2}\times 0.1=0.05moles$ of sodium sulfate.

Hence, the number of moles of $Na_2SO_4$ is 0.05 moles.

The vapor pressure of pure acetone is 266 torr. When a non-volatile solute is added, the vapor pressure of acetone above the sol

mixas84 [53]

Answer : The mole fraction of the non-volatile solute in the solution is 0.195

Explanation :

According to the relative lowering of vapor pressure, the vapor pressure of a component at a given temperature is equal to the mole fraction of that component of the solution multiplied by the vapor pressure of that component in the pure state.

Formula used :

$\frac{\Delta p}{p^o}=X_B$
