Imagine that you have a piece of Styrofoam. Suppose you squeezed it hard enough to change its shape. Briefly describe how this compression would affect its mass, volume, and density.

Express the equilibrium constant for the following reaction. P (g) + 3/2 Cl2 (g) ↔ PCl3 (g) K = [PCl3]^2/[P]^2[Cl2]^3K = [PCl3]/[P][Cl2]^3/2K = [P][Cl2]^3/2/[PCl3]K = [P]^1/2[Cl2]^1/3/[PCl3]^1/2K = [PCl3]^2/[P]2[Cl2]3
