Combustion Reactions and Environmental Pollution Flashcards

Vocabulary flashcards covering match components, ignition mechanics, and combustion definitions based on the lecture notes.

Potassium Chlorate ($KClO_3$)

A chemical compound contained in match heads that acts as an oxidizing agent.

Antimony Sulfide

A highly flammable material contained in match heads.

Match Head Components

Includes potassium chlorate ($KClO_3$), highly flammable materials such as antimony sulfide, adhesives, and glass powder or sand.

Friction Surface Components

The surface located on both sides of a safety match box, containing red phosphorus, adhesives, and glass powder or sand.

White Phosphorus

A substance formed when friction heat converts a small amount of red phosphorus, igniting spontaneously in the air to produce thermal energy.

Potassium Chloride ($KCl$)

A product formed along with oxygen gas ($O_2$) when potassium chlorate decomposes due to heat from burning phosphorus.

Ignition Temperature

The temperature at which a substance begins to burn.

Combustion

A chemical reaction between a substance and oxygen that produces heat, light, or both, and new substances that vary depending on the type of substance being burned.
