Mercury(II) oxide, a red powder, can be decomposed by heating to pro- duce liquid mercury and oxygen gas. When a sample of this compound is de-
composed, 3.87 g of oxygen and 48.43 g of mercury are produced. In a second
experiment, 15.68 g of mercury is allowed to react with an excess of oxygen
and 16.93 g of red mercury(II) oxide is produced. Show that these results are
consistent with the law of constant composition.

Particles vibrate in a rigid structure and do not move relative to their neighbors.

Water undergoes a large change in density at 0 ∘ c as it freezes to form ice. calculate the percent change in density that occurs when liquid water freezes to ice at 0 ∘ c given that
