6. In a zinc blast furnace, zinc oxide and carbon are charged into a retort (essentially a closed vessel) and heated to a sufficient temperature (1100°C) such that the reaction ZnO (s) + C (s)-Zn (vapor) + CO(g) attains equilibrium a. b. c. Is the reaction endothermic or exothermic; i.e. does the process absorb heat or give off heat? If the system contains ZnO, C, CO, CO2 and Zn (vapor), how many phases are present? At 1100°C and at equilibrium...
a Saturated solution of magnesium hydroxide is prepared and the excess solid magnesium hydroxide is allowed to settle. A 25ml aliquot of the saturated solution is withdrawn and transferred to an Erlenmeyer flask, and two drops of methyl orange indicator are added. A 0.00053 M HCl solution(titrant) is dispensed from a buret into the solution (analyte). The solution turns from yellow to a very faint red-orange after the addition of 13.2ml a. How many moles of hydroxide ion are neutralized...
6.32. A rigid vessel contains 0.014 m3 of saturated-vapor steam in equilibrium with 0.021 m of saturated-liquid water at 100°C. Heat is transferred to the vessel until one phase just disappears, and a single phase remains. Which phase (liquid or vapor) remains, ard what are its temperature and pressure? How much hieat is transferred in the process?

You have a sugar solution that is saturated and in equilibrium with a solid sugar cube (sugar cube A). You then add a second sugar cube (sugar cube B) containing radioactive sugar. After letting the solution sit overnight, you observe the next day that both sugar cubes are the same size they were the previous day. Where do you expect the radioactive sugar to be found, explain why?
