What is meant by the phrase, "the energy of an electron in a given orbital is quantized"?
flask "a" has a volume of 0.50 L and contains 50 g of a volatile liquid. Flask "b" has a volume of 1.35L and contains 34.8 g of the same liquis. Both flasks are stoppered and both are at 30C. The ratio of the vapor pressure of the liquid in the fl..
After precipitation is complete, the concentration of the OH- is -0.10M and the measured cell potential is 1.05V. Calculate the Ksp value for Zn(OH)2(s). Zn(OH)2 > Zn^(2+)(aq) + 2OH-(aq) Ksp = ? PLEASE show ALL work, I rate ALL 5 stars.
