When carbon is burned in ar it reacts with oxygen to form carbon dioxide. When 21.6g of carbon were burned in the presence of 72.8 g, 15.2 g of oxygen remained untraced. What mass of carbon dioxide was produced?

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

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.
