the combustion of 2-propanol (m = 60.0 g•mol–1 ) occurs according to the equation, 2 ch3chohch3(l) 9 o2(g) 6 co2(g) 8 h2o(l) what is q for the combustion of 15.0 g of 2-propanol?

Asolution contains 225 g of sodium chloride, nacl, dissolved in enough water to make a 0.25 l of solution. what is the molarity of the 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.

How can the periodic table be used to predict the behavior of elements?
