A student writes the following incorrect chemical equation for a single replacement reaction be- tween hydrogen chloride and aluminum
HCI + AI CI
(aq) (s) 2 (g)
+ AIH
3 (s)
Part 1:
What is wrong with the student's prediction of the products in the above reaction?
(Hint: In a single replacement reaction, part of an ionic compound is removed and replaced by a new element.)

What is a metal replacement reaction

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.
