Reactions of Metals and Non-metals with Oxygen

Flashcards covering the definitions, reactions, and laboratory processes related to the interaction of metals and non-metals with oxygen.

Oxide

A compound formed when the element oxygen reacts with another element.

Combustion reaction

The reaction of a metal with oxygen in the presence of heat.

Copper oxide

A black compound formed when reddish coloured metal copper reacts with oxygen in the air.

Iron oxide

A substance formed when iron (steel wool) burns in air.

Non-metal oxide

A substance produced when non-metals burn in air and react with oxygen.

Oxygen content in air

The percentage of oxygen found in air, which is $21\,\%$, making reactions take longer than in pure oxygen.

Laboratory preparation of oxygen

A process involving the heating of a mixture of potassium chlorate and manganese dioxide.

Downward displacement of water

The movement method used to collect oxygen gas in a laboratory setting.

Carbon combustion

Carbon (charcoal) burns in oxygen with a yellow flame to form the colourless gas carbon dioxide.

Carbon dioxide chemical equation

$$C\,(s) + O_2\,(g) \rightarrow CO_2\,(g)$$

Acidic oxide indicator test

Tests showing that an oxide is acidic, such as turning blue litmus red or turning bromothymol blue yellow.
