Given a restriction enzyme that has a concentration of 50 units/ml but your experiment requires that the concentration be reduced to 2.5 units/ml. How would you go about making 500 uL (micro liters) of diluted solution enzyme?
Determine ΔHreaction° for: 4H2O (l) + 2 NH3 (g) → 2NO2 (g) + 7H2 (g) using the following two equations: (1) N2 (g) + 3H2 (g) → 2 NH3 (g) ΔH1° = -184 kJ (2) 4NO2 (g) + 8H2 (g) → 2 N2 (g) + 8 H2O (l) ΔH2° = -196 kJ
