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.

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.

An object resting on a table weighs 100 n. with what force is the object pushing on the table? with what force is the table pushing on the object? explain how you got your answer.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
