Chemical Reactions and Equations - Vocabulary Flashcards

Vocabulary-style flashcards covering the basic definitions and concepts of chemical reactions, reactants, products, and the specific reaction of magnesium with oxygen based on the lecture notes.

Chemical reactions

Processes in which new substances with new properties are formed through chemical changes and the rearrangement of atoms.

Reactants

The substances which take part in a chemical reaction.

Products

The new substances produced as a result of a chemical reaction.

Magnesium metal

A silvery-white metal available in a science laboratory in the form of a magnesium ribbon or magnesium wire.

Magnesium oxide

A white powder produced when magnesium ribbon burns in air and combines with oxygen.

Reaction of Magnesium and Oxygen

$$\text{Magnesium (As ribbon)} + \text{Oxygen (From air)} → \text{Magnesium oxide (White powder)}$$

Dazzling white flame

The type of flame produced when a magnesium ribbon is heated and burns in air.

Sand paper

A material used to clean the magnesium ribbon before burning to remove the protective layer of magnesium oxide from its surface.
