Show the subsequent steps in the ionization of phosphoric acid including the approximate rate of ionization for each step.
boiling water at atmospheric pressure is often not enough to kill bacteria. some bacteria can survive up to 120 degrees
List two experimental conditions under which gases deviate from ideal behavior. List two reasons why the gases deviate from ideal behavior.
Problem- Draw the structure of the simple dipeptides gly-ala and ala-gly. Circle the peptide bond in each structure.
The compound NOCl decomposes to nitric oxide and chlorine according to the following equation: 2 NOCl (g) ? 2 NO (g) + Cl2 (g) Suppose that 0.420 mol NOCl is placed in a 3.00-L flask at a given temperature
Problem- A solution of a weak acid, HCOOH, is made to a concentration of 0.621 mol / L. Calculate the pH of this solution. Ka of HCOOH is 1.8 x 10-4. Enter your answer to three significant figures.
