HURRY PLEASE I'M TIMED The diagram shows the sun’s interior. Convection currents are present in the convection zone. Which best describes how fluids change as they travel through different portions of the convection currents? They change to solids at the outer portion of the convection currents. They change to solids at the inner portion of the convection currents. They become more dense at the outer portion of the convection currents. They become more dense at the inner portion of the convection currents.

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 buffer would be better able to hold a steady ph on the addition of strong acid, buffer 1 or buffer 2? explain. buffer 1: a solution containing 0.10 m nh4cl and 1 m nh3. buffer 2: a solution containing 1 m nh4cl and 0.10 m nh3
