a change in a substance that does not involve a change in the identity of the substance
A change that produces matter with a different composition than the original matter, A change that occurs when a substance chemically changes into entirely new substance with different properties.
A characteristic of a pure substance that can be observed without changing it into another substance, a characteristic of a substance that does not involve a chemical change
a property used to characterize materials in reactions that change their identity, a characteristic of a pure substance that describes its ability to change into different substances
the ability of a substance to burn
an insoluble substance formed as a result of a chemical change when two soluble substances react.
Qualitative physical property
a characteristic of a substance that can be described but not measured.
Quantitative physical property
a characteristic of a substance that can be measured (e.g density)
a homogeneous mixture of a metal with one or more metals or non metals.
a pure substance made up of two or more elements that are chemically combined (e.g., water is a compound consisting of two elements, hydrogen and oxygen).
Dalton's Atomic Theory
the proposal advanced by John Dalton (1766-1844) to explain matter, it states that all matter is made up of small particles called atoms.
a type of pure substance that can not be broken down into simpler parts by ordinary chemical means (e.g., oxygen, gold)
the smallest unit of matter that can take part in a chemical change.
