For a material to float on the surface of water, the material must have a density less than that of water (1.0 g/ml) and must not react with the water or dissolve in

it. A spherical ball has a radius of 0.50 cm and weighs 2.0 g. Will this ball float or

sink when placed in water? (Note: Volume of a sphere = 4/3(pi)(r^3)

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
