Kinetic Molecular Theory

<i>1. State the five assumptions of the Kinetic-Molecular Theory of gases.</i><br><br>a) Gases consist of large numbers of tiny particles. These particles, usually molecules or atoms, typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state. Thus molecules of gases are much further apart than those of liquids or solids.<br><br>Most of the volume occupied by a gas is empty space. This accounts for the lower density of gases compared to liquids and solids, and the fact that gases are easily compressible.<br><br>b) The particles of a gas are in constant motion, moving rapidly in straight lines in all directions, and thus passes kinetic energy. The kinetic energy of particles overcomes
<br><br><i>4. List the physical and chemical properties of gases in SQ 8.</i><br>Oxygen: Physical - Oxygen is a gas that is odorless, colorless, tasteless, and is denser than air. It appears to be a pale blue color when in liquid and solid states. Chemical - Very electronegative and tends to form oxides and peroxides.<br><br>Ozone: Physical - Ozone is a gas that is pungent, pale blue in color, and tastes bitter. Its Lewis Dot structure is resonance.<br><br>Nitrogen: Physical - Nitrogen is a gas that is odorless, colorless, tasteless, and less dense than air.<br><br>The liquid states is commonly used for freezing involving medical purposes. It appears white in its solid form. <br><br>Chemical - Because of its triple bond, nitrogen is not very reactive. It tends to react with hydrocarbons to form photochemical smog.<br><br>Ammonia: Physical - Ammonis is a gas that is strong and pungent, it is colorless, and tastes bitter.<br><br>Carbon Dioxide: Physical - Carbon Dioxide is a gas that is distinct in scent, colorless, and tastes sour. It s denser than air and its Lewis Structure is resonance.
