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.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
