Suppose you heat some mercury(II) oxide in a test tube
similar to the one shown. After
the chemical reaction, you find
12.5 g of liquid mercury and 1.0
g of oxygen gas. There is no
mercury(II) oxide left in the test
tube.
How much mercury(II) oxide
did you start with? Show your
work.

(c) the equilibrium constant is zero. (d) the value of the equilibrium constant does not show how quickly a reaction comes to equilibrium.
