Sometimes a slight change in the pH of the solution can cause denaturation of a protein. Explain why is that based on your understanding of the forces that maintain the native conformation of proteins.
Which term or terms could be used to describe this sample of gold? Check all that apply. mixture heterogeneous mixture homogenous mixture solution pure chemical substance compound element
Dinitrogen tetroxide (N2O4) dissociates via the reaction: N2O4 (g) ? 2NO2 (g). 3.00 × 10-2 mol N2O4 (g) is introduced into a 1.000L flask. At equilibrium, 2.36 × 10-2 mol N2O4 (g) remains. What is the equilibrium constant for this reaction?
