CO hydrogenation to form CH4: CO + 3H2 --> CH4 + H2O occurs on a Ru/SiO2 catalyst and is used to remove traces of CO from H2 streams used in fuel cell applications where ultra-high purity H2 is required. This reaction occurs through the following steps: (1) CO + * <--> CO* (2) H2 +2* <--> 2 H* (3) CO* + * <--> C* + O* (4) C* + H* --> CH* + * (5) CH* + H* --> CH2* + * (6) CH2* + H* --> CH3* + * (7) CH3* + H* --> CH4 + 2* (8) O* + H* <--> OH* + * (9) OH* + H* <--> H2O + 2* where steps 1, 2, 3, 8, and 9 can all be considered quasi-equilibrium. a) what is the stoichiometric number of each step?

3I- + OCl- + 2H+ ----> I3- + Cl- + H2: A 25.00 ml sample of liquid bleach was diluted to 1000 ml in a graduated flask. A 25 ml portion of the diluted sample was pipetted into an Erlenmeyer flask and treated with excess KI to oxidize OCl- to Cl- and I3- was produced at the end of the reaction. The released I3 was titrated with 0.09892 M Na2S2O3 and 8.96 ml was spent to reach the turning point besides the starch indicator. What is the percent by weight/volume of NaOCl in the bleach sample?

A solution containing 0.402 49 g of CoCl2 ? xH2O (a solid with an unknown number of waters of hydration) was exhaustively electrolyzed to deposit 0.099 37 g of metallic cobalt on a platinum cathode by the reaction Co21 1 2e2¡Co1s2. Calculate the number of moles of water per mole of cobalt in thereagent. A good approach is to find moles of Co, moles of CoCl2, mass of CoCl2, and, by difference, mass of H2O in the sample.
