A raindrop in a cloud has 320 J of potential energy due to its position above Earth. As the raindrop falls down to Earth, it gains kinetic energy. Approximately how much kinetic energy does the raindrop have the moment before it makes contact with a puddle on the ground? 0J
640 J
160 J
320 J

Anybody wanna ? (picture included? )

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
