An analytical chemist is titrating 146.1 mL of a 0.4500M solution of ammonia (NH;) with a 0.4400M solution of HNO3. The p K, of ammonia is 4.74. Calculate the pH of the base solution after the chemist has added 166.4 mL of the HNO; solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HNO3 solution added. alo Round your answer to 2 decimal places. Ar PH =

Are you able to form a negative charge because we're in a basic solution? For instance, if it were in an acidic environment, a negative charge would not persist as it is impossible to have a negative charge in an acidic environment for reaction mechanisms? And vice versa, it's impossible to have a positive charge in a basic environment for reaction mechanisms?

The overall reaction of hydroxide radical with hydrogen gas occurs as follows: OH'g) + H,(g) – H0(g) + H'(g) Part A This reaction plays a significant role in the chemistry of the earth's atmosphere by eventually converting OH to HO, through the subsequent reaction of H with O,. HO, is involved in the destruction of stratospheric ozone (J. Phys. Chem. A, 2006, 110, 6978). Determine the activation energy for the reaction of OH with H, reaction. The rate constants for the reaction of OH with H, were found to be 5.54x10 L mol s at 36. C and 1.09x10 L molrs at -27. °C. -20.9 kJ mol1 O 18.3 kJ mol1 O 25.1 kJ mol O -18.3 kJ mol O 25.1 kJ mol

Parts G and H. I thought the answers were 56.21 and 115.21 but it says they're wrong.
