Note: Figure not drawn to scale.
Students launch identical marbles of mass mm horizontally from a toy cannon of mass MC,
where Mc > mm, as shown above. The cannon can be adjusted to change the launch speed v of
the marble relative to the ground. Each time a marble is launched, the cannon slides backward
before coming to rest. The coefficient of kinetic friction between the cannon and the ground is u
(mu). For each launch, the students vary the launch speed v and record the distance x the cannon
slides backward for each launch speed.

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
