Answer:
Molecular mass, 
Explanation:
Given that,
Mass of gas, m = 0.46 g
Volume of the container, V = 515 cm^3
Pressure, P = 153 kPa
Temperature, T = 322 K
We need to find the molecular mass of this gas. We know that,
PV =nRT
n = no of moles
No of moles = mass/molecular mass
Let molecular mass is M
So, the molecular mass of this gas is 
Answer: <span>The main interactions between molecules of hydrogen chloride are examples of
Dipole-Dipole Interactions.
Explanation: The bond between Hydrogen and Chlorine is
Polar Covalent Bond as the
electronegativity difference between these two elements is
0.96 which is greater than 0.4. Chlorine being more electronegative attracts the electrons from Hydrogen making the Hydrogen
partial positive and itself
partial negative. The two poles on HCl makes it a dipole. Now, one HCl (a dipole) interacts with another HCl (another Dipole) through their opposite charges and creates
Dipole-Dipole Interaction. The picture is as below, the
green dashed lines are interactions,

Answer:
P2= 45.50 atm
Explanation:
If the amount of gas in the tanks remains same we use the equation P1T1=P2T2
40 x 281.15 = P2 x 247.15
P2= 45.50 atm
Answer:
Hydrocyanic acid.
Explanation:
Hydrocyanic acid or hydrogen cyanide is also known as formonitrile (HCN), it is a colorless, extremely poisonous liquid (because it inhibits cellular oxidative processes) which is having boiling point 26 °C, freezing point -14 °C, and highly volatile in nature.
The solution of hydrogen cyanide in aqueous is known as Prussic acid or Hydrocyanic acid. Hydrogen cyanide is used for many chemical processes such as fumigation, the concentration of ores, the case-hardening of steel and iron.
