1. Calculate the millimoles of sodium hypochlorite used in the reaction: 2.3mL of a 5.25% solution (Clorox). Compare this value with the quantity of cyclohexanol to be used in the reaction. Would you describe the oxidant as being present in slight excess or large excess?
2. How would you determine whether you have really neutralized the solution after the addition of NaOH?
3. Why is it necessary to add sodium chloride to the steam distillate before carrying out ether extraction?
The addictive painkiller morphine, C17H19NO3, is the principal molecule in the milky jiuce that exudes from unripe poppy seed capsules. Calculate the pH of a 0.0227 M solution of morphine, given that Kb = 7.9E-7.
Data: 2Ba(s) + O2(g) => 2BaO(s) ?H = -1107.0 kJ Ba(s) + CO2(g) + 1/2O2(g) => BaCO3(s) ?H = -822.5 kJ Given the data above, calculate ?H for the reaction below
