H3PO4 undergoes three ionization equilibria, for each ionization pka's 2.12, 7.21, and 12.3 respectively. A solution formed by mixing 100 mL of 0.1 M NaH2PO4 and 100 mL of 0.1 M Na2HPO4 now you just need to calculate the pH of this solution? if we want to lower the pH by one unit of this solution then How many mL of 0.1 M H3PO4 should be added to this solution?
the following compounds in order of increasing boiling point, and give reasons for your answer.
Calculate the equilibrium constant, K, for this reaction at 298 K. (b) Will Delta G increase, decrease, or stay the same if the partial pressure of NO2 is increased? (c) Calculate Delta G^o at 298K if the partial pressure of NO2 and N2O4 are 0.40 atm..
We most often express heat as kilocalories and kilojoules rather then calories and joules. When 1 pound of fat is burned in the body,9.4 kilocalories of energy is produced. Express that as a) calories b)kilojoules
