Determine the pH of a KOH solution made by mixing 0.251 g KOH with enough water to make 1.00 x 102 mL of solution.

What happened to the amount of carbon dioxide in the atmosphere from 2010–2017?

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.

Which change to the system wood cause the freely-moving piston to lower?
