a 25.0 mL sample of .050 M solution of aqueous trimethylamine is titrated with a .063 M solution of HCl. calculate pH the solution after 10.0 mL, 20.0 mL, 30.0 mL of acid have been added. pKb of (CH3)_3_N= 4.19 at 25 degrees C
Assuming all gases are at the same temperature and pressure, how many milliliters of hydrogen iodide are produced from 155 of ?
Hi Damon, thank you for your answer. With u=3.44m/s, Bob will hit the ball on the far side. The instructor showed a graph of the trajectory in class. So we know u is greater than 3.44 m/s but smaller than 5 m/s (he did a trajectory graph for u=5 m/s and Bob passed the ball by ...
Bob jumps from a 2.0 m high table and wants to jump over a 0.85 m radius ball. How fast must Bob move horizontally to not land on the ball? If we use kinematics equations for projectile, the answer is 2.66 m/s; however, with this velocity the person will land on the ball. I ne...
Identify the differences and similarities of case management in the community setting and in the managed care environment?
assume that f(x)= x^3(x-2)^2 a) find the x-intercepts algebraically b) find all the critical points c) use the first derivative test to determine local minimums and maximums d)find all inflection points e)state the concavity of the graph on appropriate intervals
Evaluate the integral from [(2/square rt 2),0] of dx/sqaure root of (4-x^2)
If x=2sec (theta), express tan(theta) in terms of x.
I have to use integration by parts to integrate tan^-1 (1/x)dx. I'm not sure what to use as u or dv. We were taught to use uv-integral of (vdu) to do this.
