What is matter with a composition that always stays the same?
A substance that always has the same composition is called a pure substance. This means it is made up of only one type of atom or molecule, leading to consistent characteristics like melting point and boiling point. Examples of pure substances include elements like gold and compounds like water.
How is water a pure substance?
Pure substances fall into two categories: elements or compounds, both of which have constant compositions. H2O is a compound, and therefore a pure substance because its composition does not vary.
A pure substance is the what throughout?
A pure substance is constant in composition throughout, meaning it is made up of only one type of particle or element. This distinguishes it from a mixture, which contains two or more different substances that are physically combined.
Does the composition of a substance always stay the same?
The composition of pure substances, such as elements and compounds, are always the same. The composition of mixtures can vary.
What is a substance with a constant composition?
No substance always has the same composition and properties, unless that substance is only considered in one of the various phases of matter. An element would be the logical choice, but many compounds and even solutions are the same no matter what (of course dependent on phase).
A classification for matter that always has the same composition?
pure substance

Sample of matter that has the same composition and properties throughout?
term for that is pure substance
Do you agree that all homogeneous matter can be classified as pure substance?
Yes, all homogeneous matter can be classified as a pure substance because it has a uniform composition throughout. This means that all samples of the matter have the same properties and composition, making it a pure substance.
What is a matter with a composition that is always the same?
Matter with a definite composition is a pure substance, such as an element, molecule, molecular compound, or ionic compound.
How is water a pure substance?
Pure substances fall into two categories: elements or compounds, both of which have constant compositions. H2O is a compound, and therefore a pure substance because its composition does not vary.
What is the definition of pure substances?
A pure substance is a substance that consists solely of the same atoms/molecules.So a volume of water that contains only H2O is a pure substance. A block of iron that contains only Fe atoms is pure substance. A pure substance can be composed of atoms or molecules as I said before BUT they have to be exactly the same.A substance that has constant chemical composition and characteristics

What is an example of a pure substance and why?
Table salt [sodium chloride], sugar [sucrose], water [H2O], Oxygen[O2] A pure substance is a substance that has a fixed composition and differs from a mixture in that every sample of a given of a pure substance has exactly the same characteristic properties and compositions.
Does the composition of a substance always stay the same?
The composition of pure substances, such as elements and compounds, are always the same. The composition of mixtures can vary.

What is the characteristic of a pure substance?
The defining characteristic of a pure chemical substance is that any sample of it contains the same elements in the same mass proportions to one another.
