two farmers notice that some bean plants are much taller than others, even though they are growing in the same field. Farmer A thinks the difference in height is due to inheritance. Farmer B thinks it is because some plants in the field get more water than others. Describe an experiment that will provide evidence for farmer B to prove he is right.

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.
