Hi can someone show me how to solve these
Cinnamic acid is obtained from oil of cinnamon. 125 millimoles of HCI were added to a solution containing 0.2 moles of a cinnamic acid and 0.3 moles of its conjugate base. After mixing, the pH of the solution was found to be 4.17. What is the pK, of cinnamic acid? A) 4.44 B) 4.17 C) 3.90 D) 4.93 E) 4.66 The digestive enzyme pepsin is secreted by stomach cells into an...

Can anyone explain these
formulas to me? They are for the propagation of uncertainty (with y
= final result and ey = the error of y). I am mostly
unsure about the use of natural log, and how exactly to use them
when trying to find error - an example would be much
appreciated.

Can anyone tell me how to can the -3 and
+5 on the of N? I know -3 to +5 is oxidized. But I don't know where
is -3 and +5 come from.
Same question how do you get 0 and +4?
-3 +1 +1 +5 -2 NH3(aq) + 20%(9) ► HNO3(aq) + H20(1) The oxidation state of the nitrogen atom is – 3 before the reaction and +5 after the reaction. That means the nitrogen atom is oxidized. +4...
