The ph of blood is 7.35. it is maintained in part by the buffer system composed of carbonic acid (h2co3) and the bicarbonate (hydrogen carbonate, hco3-) ion. what is the ratio of [bicarbonate]/[carbonic acid] at this ph? for carbonic acid, ka1 = 4.2 10-7.a) [bicarbonate]/[carbonic acid] = 0.11d) [bicarbonate]/[carbonic acid] = 9.4b) [bicarbonate]/[carbonic acid] = 0.38e) none of the above ratios is correct. c) [bicarbonate]/[carbonic acid] = 2.65

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?

Scientists often have to deal with numbers that are either very large or very small. for example, the radius of the sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. express each number in an alternate form.
