a) Write a balanced reaction for the process of reacting potassium with oxygen to form potassium oxide, or K2O. b) Suppose 10.0g of potassium reacts with excess oxygen gas, and 10.5 g of K2O is produced. What is the percent yield? c) Now suppose 4.0g of potassium and 1.0g of oxygen gas react in a closed flask. How much K2O can be produced?
