10. True or False (use your periodic table/data sheet when appropriate) а. The cation formed from a neutral atom is always smaller than the neutral atom. b. The Celsius temperature of a gas is directly proportional to the average kinetic energy of the gas particles. The H-Br bond is more polar than the H F bond. NO, is the conjugate acid of the base, HNO2. A postulate of “The Kinetic Molecular Theory of Gases" is that gas particles do not attract each other. A solution with a pOH of 7.5 has a greater concentration of hydrogen ions than a solution with a pOH of 5.6. As the volume of a gas decreases, the pressure the gas exerts on its container increases (assume n & T remain constant). Real Gases approach Ideal Gas behavior at low Pressures and low temperatures. A solution with a pH of 6.3 has a greater concentration of hydroxide ions than a solution with a pH of 4.5. HCO3 (aq) is an amphiprotic substance. Vapor is any substance in the gaseous state that is usually a liquid or solid.…
