Carbon -14 has a half- life of 5715 years. If a sample of carbon-has and original mass of 12g, what will be the amount remaining at the end of 10, 788 years ? Write out your equations and type out your calculations to show your work to the best of your ability. Answers should have the correct number of significant figures and unit.

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.
