In comparison with liquids and gases, solids are
a. more dense.
b. more easily compressed.
c. less organized.
d. more likely to flow.

In comparison with liquids and gases, solids are more dense. The answer is letter B. The solid has a more definite shape and volume. The particles are locked into place. It cannot be further compressed due to the bond that exists between the molecules. The kinetic energy of the molecules is close to none because the molecules are so close and so compact with each other. 

Only one reactant yields 2 or more products. meaning you will only have 1 product and it will break down into 2 or more products. eg. h2o -> h2 + o2
