In an attempt to measure the effects of acid rain, researchers measured the pH (7 is neutral and values below 7 are acidic) of water collected from rain in Gurabo, Puerto Rico. 5.40 5.37 5.38 4.63 5.39 3.74 3.71 4.96 4.64 5.12 5.65 5.36 4.16 5.87 4.57 4.62 5.48 4.57 4.57 4.53 4.82 4.52 4.69 4.32 3.98 5.70 4.35 3.98 5.68 3.44 5.04 4.67 4.51 4.34 4.16 4.64 5.12 3.74 4.64 5.59 Draw the correct histogram. Many scientists consider rain with pH below 5.3 to be acid rain. What percentage of these samples could be considered as acid rain? Note: You may MS Excel, but you must submit the file
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.…
