term for that is pure substance
A uniform mixture is : A sample of matter that has the same composition and properties throughout.
A sample of matter is considered homogeneous if its composition and properties are uniform throughout. This means that the sample has the same characteristics, such as color, density, and chemical composition, in all its parts. This uniformity allows for consistent behavior and properties within the sample.
Homogeneous matter has the same composition and properties throughout, like air or sugar water. Heterogeneous matter has varying compositions and properties within the sample, like a fruit salad or a mixture of oil and water.
A sample of matter is considered homogeneous when its composition is uniform throughout, meaning the components are evenly distributed at a molecular level. This results in consistent physical and chemical properties in all parts of the sample.
A substance is matter that has a uniform and consistent composition, meaning it contains the same types and proportions of atoms or molecules throughout. This results in substances having characteristic properties that do not vary within the sample.

Sprite is a homogeneous mixture because it is uniform throughout and the composition is the same no matter where you sample from.
Since gold is an element and therefore a pure substance it is homogeneous.
Chemistry is the scientific study of the composition structure and properties of matter and the changes that it undergoes.
During a physical change, the chemical composition of the matter remains the same, while its physical properties, such as shape, size, or state, may change. The individual particles that make up the matter do not change in a physical change.
Several chemical properties can be estimated knowing the chemical composition.
Mass is an extensive property, which depends only on the amount of matter in the sample, not on the composition of the sample.
