This looks like a pretty basic question, although asked out of context, it is tricky. The same composition is called "definite" composition. The more technical term should make us think of the classification of matter. Pure substances have definite composions as opposed to mixtures that have variable composition.
Your answer is pure substances. Pure substances can be either compounds, made of 2 or more kinds of atoms or elements make of 1 kind of atom.

What is a pure substants?
A pure substance is a material that has a constant composition and distinct properties. It is made up of only one type of atom or molecule. Examples include elements like gold and compounds like water.
The composition of a mixture can vary unlike a compound?
Yes, in a mixture, the substances are physically combined and can be present in any proportion. This allows the composition to vary, unlike a compound where the elements are chemically combined in fixed ratios.
What is the phase of matter with no fixed shape but fixed volume?
The phase of matter with no fixed shape but fixed volume is a liquid. Liquids take the shape of their container but maintain a constant volume because the particles are close together but can move past each other.
How are pure matter and mixed matter different?
A pure matter in any form , gas, liquid or solid will maintain a unique unchanged chemical and physical charcateristics. Meanwhile, mixed matter has a wide range of character depending on the ingredient of the content
What is a substance is science?
In science, a substance is a specific type of matter that has constant chemical composition and characteristic properties. Substances can be elements, compounds, or mixtures, and they can exist in different phases (solid, liquid, gas). Examples include water (H2O) as a compound and gold (Au) as an element.
What is any matter that has a fixed composition and definite properties?
A substance is any matter that has a fixed composition and definite properties. This means that substances are made up of specific elements in a certain ratio, and they exhibit unique characteristics that can be used to identify and describe them. Examples of substances include water (H2O), salt (NaCl), and oxygen (O2).
Explain why the composition of an element is fixed.?
The composition of an element is fixed because each element is made up of a unique type of atom with a specific number of protons in its nucleus. This number of protons determines the element's identity, and any change in the number of protons would result in a different element. Therefore, the composition of an element cannot be altered without changing its identity.
What kinds of matter are present in any amounts?
In any given sample of matter, you can typically find elements, compounds, and mixtures present in varying amounts. These can include atoms, molecules, ions, and particles such as electrons and protons. Each type of matter contributes to the overall composition and properties of the sample.
What is the atomic formula for wood?
Wood is not a compound of fixed composition and therefore does not have any single chemical formula.
What is a pure substants?
A pure substance is a material that has a constant composition and distinct properties. It is made up of only one type of atom or molecule. Examples include elements like gold and compounds like water.
What is the word for any type of matter?
Substance is a word that can be used for any type of matter. The substance in the jar was neither liquid or solid.
What are the most common type of dace?
any type no matter what:)
What is the definition of fluid?
A fluid is any matter that has no fixed shape, can flow and takes the shape of its container.
What is the most general name for any single type of matter that is made from a specific arrangement of atoms?
A chemical compound is the most general name for any single type of matter made from a specific arrangement of atoms. It consists of two or more different elements bound together in a fixed ratio by chemical bonds.
What describes any change in matter that does not affect the chemical composition of the material?
Physical change, as change in state.
The composition of a mixture can vary unlike a compound?
Yes, in a mixture, the substances are physically combined and can be present in any proportion. This allows the composition to vary, unlike a compound where the elements are chemically combined in fixed ratios.
Any type of matter that flows or can be poured?
Liquid.
