What are the general properties of gases?

Does the identity of a gas matter when using Boyle's law? Why or why not?

List these intermolecular interactions from weakest to strongest: London forces, hydrogen bonding, and ionic interactions.

The balanced chemical equation for the combustion of propane is as follows: $$ C_{3} H_{8(g)}+5 O_{2(g)} \rightarrow 3 C O_{2(g)}+4 H_{2} O_{(\ell)} $$ a. If \(100.0 \mathrm{~g}\) of propane are combusted, how many moles of oxygen gas are necessary for the reaction to occur? b. At STP, how many liters of oxygen gas would that be?

What phase or phases have a definite volume? What phase or phases do not have a definite volume?

Why does the kinetic theory of gases allow us to presume that all gases will show similar behavior?

Does the identity of a gas matter when using Charles's law? Why or why not?

The equation for the formation of ammonia gas \(\left(\mathrm{NH}_{3}\right)\) is as follows: $$ N_{2(g)}+3 H_{2(g)} \rightarrow 2 N H_{3(g)} $$ At \(500^{\circ} \mathrm{C}\) and \(1.00 \mathrm{~atm}, 10.0 \mathrm{~L}\) of \(\mathrm{N}_{2}\) gas are reacted to make ammonia. a. If the pressures and temperatures of \(\mathrm{H}_{2}\) and \(\mathrm{NH}_{3}\) were the same as those of \(\mathrm{N}_{2}\), what volume of \(\mathrm{H}_{2}\) would be needed to react with \(\mathrm{N}_{2}\), and what volume of \(\mathrm{NH}_{3}\) gas would be produced? b. Compare your answers to the balanced chemical equation. Can you devise a "shortcut" method to answer Exercise \(4 \mathrm{a}\) ?
