This flashcard set covers key concepts related to the classification of matter, including various chemical substances and their properties.

Phosphoric acid (H3PO4)

Can be used as an additive in foods such as jams and sodas, giving them a tangy or sour taste; can also remove rust.

Potassium chromate (K2CrO4)

A stable, yellow, crystalline solid that is very toxic and may be fatal if swallowed; it is a carcinogen.

A flammable solvent that evaporates quickly, known to cause skin and respiratory irritation, often found in nail polish removers.

Methanol (CH3OH)

A highly toxic alcohol; ingesting small amounts can cause blindness and neurological damage.

Sulfuric acid (H2SO4)

A highly soluble, viscous liquid commonly found in car batteries and industrial cleaning agents.

CCl4 + 2H2

Represents a chemical reaction involving the compound Carbon Tetrachloride and hydrogen molecules.

Chemical formula

A symbolic representation of the elements in a compound, indicating the number of atoms of each element.

Element

A substance that cannot be broken down into simpler substances and is made up of only one type of atom.

Compound

A substance formed when two or more elements are chemically bonded together.

Mixture

A combination of two or more substances in which each substance retains its individual properties.

Evidence

Supporting information used to classify matter as an element, compound, or mixture; examples could be chemical formulas or descriptions.
