A94.7-g sample of silver (s = 0.237 j/(g · ° initially at 348.25°c, is added to an insulated vessel containing 143.6 g of water (s = 4.18 j/(g · ° initially at 13.97°c. at equilibrium, the final temperature of the metal–water mixture is 22.63°c. how much heat was absorbed by the water? the heat capacity of the vessel is 0.244 kj/°c.

If a polyatomic ionic compound has gained two hydrogen ions, then how does its name begin?

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.
