One method proposed for removing SO2 from the flue gases of power plants involves reaction with aqueous H2S. Elemental sulfur is the product.
(a) Write a balanced chemical equation for the reaction.
(b) What volume of H2S at 27 °C and 760 torr would be required to remove the SO2 formed by burning 2.0 tons of coal containing 3.5% S by mass?
(c)What mass of elemental sulfur is produced? Assume that all reactions are 100% efficient.
To measure the volume of an irregularly shaped container filled with water, 1.00 ml of 2.00 M potassium chloride solution is added. After stirring, a 5.00 ml sample was found to contain 2.54x 10^-2 mg of potassium ion. What is the volume of the co..
Calculate the enthalpy change per mole for this process. ( Assuming C=4.18 J deg c^-1 g^-1 and density of the final solution is 1.00g/ml).
What systematic factors in the experience itself may lead to an answer that is not exactely correct.( Do not include student errors such as 'I forgot to set the balance to 0",etc.We assume the student is a perfect experimenter and errors result on..
