An egg is placed at the bottom of a bowl filled with water. salt is slowly added to the water until the egg rises and floats. from this experiment, one can conclude that
a) the density of salt water exceeds the density of egg.
b) calcium in the eggshell is repelled by sodium chloride.
c) buoyant forces do not always act upward.
d) salt sinks to the bottom.
e) none of the above
