Unformatted text preview: temperature? What is the white powder? Boiling point of helium: 4.2K; of argon -185.7 o C. Melting point of argon -183 o C Question 3 Air+HCl(g) Air +NH3(g) Two sturdy compartments of 1 cubic meter each are filled with gas mixtures and separated by a thin wall. On the left is air containing a concentration of 0.5 [mol/L] of HCl gas. On the right is air with 0.25 [mol/L] ammonia gas. Both compartments are are 25oC and 1 atmosphere total pressure. The thin wall is punctured and a white fog of solid ammonium chloride is formed that slowly precipitates into a thin dust of the floor of the containers. How many moles and grams of HCl are in the left compartment before the wall is punctured? What is the final pressure of the gas in the container? What is the limiting reactant? What is the mass of the solid ammonium chloride formed?...
