Standing: Stood with min assist x 2, holding onto rolling walker, weight primarily on RLE, L foot turned out, patient had dizziness which eased as she stood longer. Ambulation: Patient was unable to take steps with rolling walker. Unable to stabilize left knee for stance, unable to flex left hip for swing. 8

Given that the radius of the electron’s orbit is 5.29x10-11m, and its mass is m e=9.11x10-31km. Find the electron’s speed.
Sample Exercise 16.1 Identifying Conjugate Acids and Bases
www.austincc.eduThis is a proton- transfer reaction, and the position of the equilibrium will favor the proton going to the stronger of two bases. The two bases in the equation are CO. 3 2–, the base in the forward reaction as written, and SO. 4 2– the conjugate base of HSO. 4 –. We can find the relative positions of these two bases in Figure 16.4
