What would happen to the average kinetic energy of the molecules of a gas sample if the temperature of the sample increased from 20c to 40c

If i can still dissolve more sugar into the solution at a certain temperature what would i call that solution

Which diagram shows the correct way to represent an ionic compound of magnesium oxide?

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.
