You have 125.0mL of a solution of H3PO4, but you don't know its concentration. If you titrate the solution with a 4.56M solution of NaOH and reach the endpoint when 134.1mL of the base are added, what is the concentration of the acid?

The peak wavelength for the blackbody curve of a star is in the uv range. assuming the radiation from this star can reach earth, would you be able to see it?

If 90.0 grams of ethane reacted with excess chlorine, how many grams of dicarbon hexachloride would form

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.
