Chem 171 Quiz 6 Version A (5 pts each) (Show work, unit, sig fig for full credit) (Key CO 2 / TernMix) 1. What is pressure? Why is moist air less dense than dry air? N= 14.01; O=16.00; Ar=39.95. H=1.008. PV = nRT. R = 0.08206 L atm mol -1 K -1 . 1 atm = 101,325 Pa = 760 Torr. g = 9.80665 m / s 2 . 1 kgm/s 2 = 1 N. 1 N/m 2 = 1 Pa. P=hdg. Pressure = Force / area Air is mostly N 2 (28.02 g/mol), O 2 (32.00 g/mol), and argon (39.95 g/mol). These “heavy” gases dominate the density of dry air. Moist air contains H 2 O (18.02 g/mol). The relatively light water molecules lower the density of the moist air. 2. The following questions refer to the experiment entitled “Physical Separation of a Ternary Mixture”: What is a mixture? Name the significant product that is formed when a sulfide is reacted with a strong acid; state whether the product is a solid, liquid or gas. Name the significant product that is formed when a carbonate is reacted with a strong acid; state whether the product is a solid, liquid or gas. A mixture is a combination of two or more substances in which the substances retain their distinct identities. H 2 S (g) CO 2 (g) Chem 171 Quiz 6 Version B (5 pts each) (Show work, unit, sig fig for full credit) 1. Define pressure.
