Two substances, a and b, initially at different temperatures, come into contact and reach thermal equilibrium. the mass of substance a is 6.03 g and its initial temperature is 20.3 °c. the mass of substance b is 25.9 g and its initial temperature is 52.4 °c. the final temperature of both substances at thermal equilibrium is 46.2 °c. if the specific heat capacity of substance b is 1.17 j/g·°c, what is the specific heat capacity of substance a?

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.

Consider the story you just read. all but one of the choices below indicate that something is living.

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
