3. What is the difference between strong acids and bases versus weak acids and bases?
In strong acids and bases, the solute's ions go to completion and dissolve in the solution. In weak acids and bases, the reaction does not go to completion, and they will dissolve only slightly.
In strong acids and bases, the reaction does not go to completion, and they will dissolve only slightly. In weak acids and bases, the solute's ions go to completion and dissolve almost completely in the solution.
In strong acids and bases, there is no reaction. In weak acids and bases, there is a strong chemical reaction.
In strong acids and bases, the pH is lowered after the reaction. In weak acids and bases, the pH increases after the reaction.

Which describes an image that can be produced by a concave lens? the image is real and smaller than the object. the image is virtual and larger than the object. the image is virtual and smaller than the object. the image is real and larger than the object.

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
