You have at your lab bench the following chemicals: nah2po4 (s), na2hpo4 (s), na3po4 (s), nh4cl(s), nach3coo(s), 1.0 m ch3cooh(l), 1.00 m nh3, 1.00 m naoh, 1.00 m hcl, and deionized water. you also have standard glassware available. describe how you would make 500 ml of buffer with a ph of 5.00 using only pure materials and deionized water so that the total concentration of the conjugate acid/base pair is 0.200 m

What is the name of this hydrocarbon?

Name the element in group 17, period 2. (periodic table)

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.
