HELP PLEASE!! Bill used a first class lever to lift a heavy boulder that requires 200 N of
force to be lifted. He pushed down on one end of the lever with 50 N of
force. This end of the lever went down 0.5 m. This resulted in the boulder
lifting 0.1 m. What was the mechanical advantage of the lever? Please
record the NUMERICAL VALUE only.

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
