A bubble rises from the bottom of a lake of depth 90.0 m, where the temperature is 3° C. The water temperature at the surface is 18° C. If the bubble's initial diameter is 1.00 mm, what is its diameter when it reaches the surface? (Ignore the surface tension of water. Assume the bubble warms as it rises to the same temperature as the water and retains a spherical shape. Assume Patm = 1.0 atm.) mm
Correct the second part of each of the following statements. (Type your answer using the format copper(II) chloride for CuCl2, and CO2 for CO2.) (a) SF6 is sulfur heptafluoride. (b) Phosphorous pentachloride is Cl5P. (c) Carbon tetrachloride is CC..
Consider an electrochemical cell with a cobalt electrode immersed in 1.0 M Co2+ and a lead electrode immersed in 1.0 M Pb2+. Co2+ + 2e- --> Co E0 = -0.28 V Pb2+ + 2e- --> Pb
