A vinegar solution of unknown concentration was prepared by diluting 10.00 mL of vinegar to a total volume of 50.00 mL with deionized water. A 25.00 mL sample of a diluted vinegar solution required 20.24 mL of 0.1073 M NaOH to reach the titration equivalence point. Calculate the concentration of acetic acid (in M) in the original vinegar solution (before dilution).

Acompound contains c, h, and o atoms. when 1.130 g of the compound is burned in oxygen, 1.064 g co2 and 0.3631 g h2o are produced. what is the empirical formula of this compound?

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.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt
