A 9.00 3 102 -mL 0.200 M MgI2 was electrolyzed. As a result, hydrogen gas was generated at the cathode and iodine was formed at the anode. The volume of hydrogen collected at 26C and 779 mmHg was 1.22 3 103 mL. (a) Calculate the charge in coulombs consumed in the process. (b) How long (in min) did the electrolysis last if a current of 7.55 A was used? (c) A white precipitate was formed in the process. What was it and what was its mass in grams? Assume the volume of the solution was constant.
GEOL 207 Environmental Geology More Atmosphere Stuff!! - Albedo reflection of light on earth. o Clouds - Air and atmosphere in a system o Circular system (atmosphere) Much faster than other circular systems such as plate tectonics. - CIRCULAR SYSTEMS (air) o Energy comes from the sun o Buoyancy The ability or tendency to float in water or air or some other fluid. Factors Pressure Volume Temperature If factor (variable) is constant, you can omit it from the equation - Lateral Movement o Sideways movement Wind travels from high pressure to low pressure Air follow pressure gradients - ITCZ Inter tropical convergence zone o Is the area encircling the earth near the equator where the northeast and southeast trade winds come together o o Coriolis Effect An effect whereby a mass moving in a rotating system experiences a force (the Coriolis force) acting perpendicular to the direction of motion and to the axis of rotation. On the earth, the effect tends to deflect moving objects to the right in the northern hemisphere and to the left in the southern and is important in the formation of cyclo
