The temperature near the floor of a room is about 68.7 F. The temperature near the ceiling 77.2F. What is the difference in density of the air at the top and bottom of the room? (Hint: assume that the volume and pressure is the same, if you like, you can take the volume to be 1L and the pressure to be 1atm, but if you think carefully you may realize that this is not necessary.)
Scientists can use mutants to study metabolic pathways. These organisms have a mutation in a gene encoding a metabolic pathway enzyme that results in the inactivation of that enzyme
Calculate the pH of a buffer solution that contains 0.25 M benzoic acid (C6H5COOH) and 0.15 M sodium benzoate (C6H5COONa). Ka= 6.5 x 10^-5 for benzoic acid. Please show your work for how you got this.
