Triphenylmethanol is insoluble in water, but when it is treated with concentrated H2SO4, a bright yellow solution results. As this yellow solution is diluted with water, its color disappears, and a precipitate of triphenylmethanol reappears. Suggest a structure for the bright yellow species.

Amount of liquid measured in l or lm

The mass of a neutron is equal to the mass of a proton plus the mass of an electron. true or false false true

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.
