Which substance is made up of same kind of elements?

Which substance is made up of same kind of elements?

Compound
Element : A pure substance composed of the same type of atom throughout. Compound : A substance made of two or more elements that are chemically combined in fixed amounts.

What are the proportions of substances in a mixture?

A mixture is a combination of two or more substances in any proportions. The substances in a mixture do not combine chemically, so they retain their physical properties. A homogeneous mixture has the same composition throughout. A heterogeneous mixture varies in its composition.

Is a compound made of the same element in definite proportions?

The law of definite proportions states that a given chemical compound always contains the same elements in the exact same proportions by mass.

Is substance and element the same?

Elements and Atoms. An element is a pure substance. It cannot be broken down into other types of substances. Each element is made up of just one type of atom.

What do we call a substance that is the same throughout?

A solution is a mixture that is the same or uniform throughout. Think of the example of salt water. This is also called a “homogenous mixture.” A mixture that is not a solution is not uniform throughout.

What is having same kind of atoms?

The answer is element.

What do we call a substance that is the same throughout answer?

A pure substance is a form of matter that has a constant composition (meaning that it is the same everywhere) and properties that are constant throughout the sample (meaning that there is only one set of properties such as melting point, color, boiling point, etc. throughout the matter).

What do you call a substance that is the same throughout?

A solution is a mixture that is the same or uniform throughout. Think of the example of salt water. This is also called a “homogenous mixture.” A mixture that is not a solution is not uniform throughout. Think of the example of sand in water.

What is the chemical combination of two or more elements in definite proportions?

Compounds
Compounds are made up of two or more elements combined in definite quantities and in definite proportions by chemical bonds. Substances are pure forms of matter that cannot be separated or purified further by physical means; include compounds and elements.

Which law states that in a chemical substance same elements are present in fixed proportion by mass?

the law of definite proportion
In chemistry, the law of definite proportion, sometimes called Proust’s law, or law of constant composition states that a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.

What is the difference between substance and matter?

Anything that occupies space and has mass is matter but the matter that has specific composition and chemical characteristics is substance.

What is difference between substance and mixture?

a pure substance consists only of one element or one compound. a mixture consists of two or more different substances, not chemically joined together.
