What is a material that contains three elements joined in a fixed proportion?
If a material contains three elements joined in a fixed proportion, then it is a compound. It can only be separated by a chemical reaction.
One difference between a compound and a mixture is a compound always?
A compound is composed of two or more elements chemically combined in a definite proportion. The components of a mixture are not chemically combined and can vary in proportion.
Every chemical compound is unique and different from the it contains.?
Every chemical compound is unique and different from the ELEMENTS it contains
Why rubber have the same empirical formula as its monomer?
An empirical formula only takes into account the proportions of the elements in a compound. The proportion of elements in a polymer might be the same or similar as the proportion in the monomer from which it is made.
Whats the difference between a compound and a mixture?
a compound is a substance that contains two or more elements chemically combined in a fixed proportion while mixture is a physical blend of two or more substances that are not chemically combined
What is a material that contains three elements joined in a fixed proportion?

What is meant by law of constant proportion and how is this law applied in experiment empirical formula of a compound?
The law of constant proportion states that a pure chemical compound always contains exactly the same proportion of elements by mass.This information, together with the atomic masses of the elements in the compound enable scientists to determine the formula of a compound.
What substance that contains 2 or more elements chemically combined in a fixed proportion?
A substance made of two or more elements chemically combined in a specific proportion is called a compound. A substance composed of two or more elements combined chemically in a fixed proportion by mass is called a compound. A chemical compound can be held together by a covalent bond or an ionic bond.
Is it true that water is not a binary compound because a water molecule contains three atoms?
No.Water is a binary compound. A binary compound contains two elements, regardless of the number of atoms of each.
What is the rule of constant proportions?
The law of constant proportions, also called Proust's law, states that the elements in a compound are all present in a fixed proportion by weight, regardless of how the compound is prepared.
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 notion that shows what elements a compound contains and the ratio of the atoms or ions of these elements in the compound?
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
