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.
What are two or more substances that are chemically combined in a fixed proportion called?
Compound
How can we determine that water is a compound not a mixture?
Water is a compound because its molecules are formed of chemically combined elements (hydrogen and oxygen) in a fixed proportion. A mixture is a combination of separate atoms, molecules, or particles that are not chemically bonded or in any fixed proportion.
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.
Are the elements that make up a compound joined in a fixed proportion?
This is an old rule (Law of definite proportions) not valid for nonstoichiometric compounds.
What is compound and a example?
compound contains elements in a fixed proportion. Example= NaCl
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.
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 is the name of two or more elements in a fixed proportion?
A compound refers to two or more elements chemically bonded together in a fixed proportion. This fixed proportion is represented by a chemical formula that shows the types and ratios of atoms present in the compound.
What can atoms can be blended in any proportion within?
ionic compound
Atoms or ions can be blended in any proportion within a?
covalent 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.
What are two or more substances that are chemically combined in a fixed proportion called?
Compound
What theory states that a given compound will always contain exactly the same proportion of elements by weight?
Law of definite proportion or law of definite composition.

A given compound is always made of the same elements in the same proportion.
A compound differs from a mixture because it?
always contains the same elements in the same proportion.
What describes a substance formed by the combination of two or more element in a definite proportion?
