Copper and zinc (elements 29 and 30, respectively) appear next to each other on the periodic table. A 5.50 g sample of zinc has a volume of 0.770 mL, while a 5.50 g sample of copper has a volume of 0.616 mL. Why?
What concentration should you make your stock solution of vincristine in order to make this 5uL addition?
sketch the corresponding Gibbs free energy curve showing all phases that appear on the sketch. Indicate the equilibrium phase compositions.
Given the following equilibrium constants at 427 °C: Na2O(s) 2Na(l) + 1/2 O2(g) Kc = 2 x 10-25 NaO(g) Na(l) + 1/2 O2(g) Kc = 2 x 10-5 Na2O2(s) 2Na(l) + O2(g) Kc = 5 x 10-29 NaO2(s)
