Write the overall cell reaction for the galvanic cell given below. pt(s) h2(g) h+(aq) cl2(g) cl-(aq) pt(s) a) pt(s) + h2(g) + cl-(aq) → pt(s) + 2 h+(aq) + 2 cl2(g) b) 2 h+(aq) + 2 cl2(g) → 2 hcl(aq) c) h2(g) + cl2(g) → 2 h+(aq) + 2 cl-(aq) d) no reaction would occur because there is no salt bridge. c

What layer of the atmosphere is directly above the troposphere?

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
