What is matter with a composition that always stays the same?
Matter with a definite composition is a pure substance, such as an element, molecule, molecular compound, or ionic compound.
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.
Why does the chemical composition of water always stay the same?
Because water is a compound, a type of pure substance, which has a definite composition.
What are substances in which the composition is the same throughout?
If it is a pure substance, then it is a molecule or formula unit. If it is a mixture, it is a solution.
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).
What is matter with a composition that always stays the same?

A classification for matter that always has the same composition?
pure substance
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.
Sample of matter that has the same composition and properties throughout?
term for that is pure substance
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
Why does the chemical composition of water always stay the same?
Because water is a compound, a type of pure substance, which has a definite composition.
What is pure substance in thermodynamics?
a pure substance is a substance that entails unchanging/unvarying molecular structure
What are substances in which the composition is the same throughout?
If it is a pure substance, then it is a molecule or formula unit. If it is a mixture, it is a solution.
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.
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.
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).
What is any type of matter with a fixed composition?
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.
