Reactions that cause change of oxidation numbers are called redox reactions.

Reactions that cause change of oxidation numbers are called redox reactions. Element loses electrons ? its oxidation number increases ? element is oxidized ? oxidation reaction. Substance that contains the oxidized element is call the reducing agent.

Properties of Gases

Density of air (outside) = 1.2 mg/mL. Density of air (inside) = 0.88 mg/mL. Properties of Gases. Pressure: the pressure of a gas is caused by the gas particles colliding with the walls of the container. Pressure is always a force exerted over an area. (P = F/A)
