Given the following info about a 1L solution determine the final pH of the buffer after the addition of strong acid. Initial HAc = 0.71

Initial pH = 5.12

Ka = 1.8x10-5

To the buffer was added 0.068 moles of HCl.

-1*log((1.8*10^-5*(X-Z)/(1.8*10^-5* X/(10^-Y)+Z)))

How is 0.00235 expressed in proper scientific notation? a. 2.35 × 10-3 b. 0.235 × 10-2 c. 2.35 d. 2.35 × 103

Alidded glass container is filled with a colored gas. after a period of time, it is observed that the gas is uniformly spread throughout the box and that the movement has slowed considerably. next, a warm iron plate is carefully placed under the box. why is there resumed movement of the gas in the container?

Kp is the equilibrium constant for dissociation of the propionic acid dimer. what is the sign of the slope for a plot of the natural logarithm of kp vs. inverse temperature for this reaction?
