Does the composition stays the same or pure substance?
A pure substance consists of only one type of element or compound. The composition of a pure substance always stays the same, with a fixed ratio of its constituent particles.
Do compounds always contain the same elements in the ratio?
No, compounds do not always contain the same elements in the same ratio. Compounds are formed by the combination of two or more elements in fixed proportions by mass. The ratio of elements in a compound is determined by the chemical formula of the compound.
Who said that a given compound always contains the same elements in the same proportions by mass?
This statement was made by French chemist Joseph Proust and is known as the Law of Definite Proportions. It states that a compound always contains the same elements in the same proportions by mass regardless of the source of the compound.
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.
What is the law of definite proportions?
A chemical compound always contains exactly the same proportion of elements by mass. ---------------------------------------------------------------------------------------------------- A law that states that a compound always contains the same elements in the same proportions. Source: e2020

A given compound is always made of the same elements in the same?
A given compound is always made of the same elements in the same proportion.
What stays the same but always changes?
nothing, atoms are always moving.
What does a compound have that is always in a particular compound?
Same type of atoms.
Is the law of definite proportions says that the composition of a compound always the same?
always the same
Is the amount of elements needed to make a compound always the same?
The proportions are always the same.
Does a compound always contain the same element in the same proportions?
Yes, except that "element" should be pluralized; a compound always has at least two elements.
What do you call a variable in an experiment that always stays the same?
constant variable
What gains and loses weight but always stays the same shape?
Scales
Are elements that make up a compound always present in the same proportions?
No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.

What changes with location mass or weight?
weight.. Mass always stays the same
