what are the difference between elements and mixtures?
479879
Elements are the purest form of a chemical substance and are composed of only one type of atom. In other words, all of the atoms in an element will have the same number of protons. ... A mixture is a combination of two or more different chemical compounds or elemental substances.

A mixture is formed when 2 or more different material/objects are put together. A solution is created when mixing a solid and liquid together and a the solid disappears or dissolves. A compound is 2 or more elements chemically combined together.

The mixture is a substance made by the physical combination of two or more different elements or compounds. A mixture does not involve any chemical reaction. ... Alloys are mixtures of one or more metals in a solid solution.

Difference Between Mixtures and Compounds. The mixture contains two or more substances mixed, but neither chemically as well as not in inexact quantity while compound includes two or more elements combined chemically and in a fixed ratio. ... Even matter can be classified into two classes, mixtures, and the pure substances ...

Answer: A pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample. Mixtures are physical combinations of two or more elements and/or compounds.

Matter is classified into two broad categories, namely, pure substances and mixtures. Mixtures can be separated into pure substances by physical methods. Pure substances are further divided into categories as elements and compounds.

['the substances in mixtures are in different proportions.', 'the melting and boiling points vary. they depend on the composition of the mixture.', 'substances within mixtures keep their own properties.', 'substances in mixtures can be separated by physical methods.']

Compounds are two or more elements chemically combined in definite proportions by weight. Mixtures are two or more substances not chemically combined.

A mixture is when two or more substances combine physically together. However, in water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone. ... Therefore, water is not a mixture; it is a compound and it is pure.

A mixture is 2 or more substances which have been mixed together but which have not chemically bonded. Air is a mixture. It contains nitrogen, oxygen, carbon dioxide, a small amount of inert gases and some moisture. The proportions of these substances are not fixed.

A mixture is the blending of two or more dissimilar substances. A major characteristic of mixtures is that the materials do not chemically combine. Mixtures can be divided into those that are evenly distributed (homogeneous) and those that aren't (heterogeneous).

A pure substance (an element or a compound) is made up of only one type of atom, or molecule. Examples: water (H2O molecules), oxygen (O2 molecules), argon (Ar atoms). A mixture is made of up of more than one type of atom or molecule.

A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded.

A homogeneous mixture in which there is both a solute and solvent present is also a solution. Mixtures can have any amounts of ingredients. Mixtures are unlike chemical compounds, because: The substances in a mixture can be separated using physical methods such as filtration, freezing, and distillation.

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.
984982
Mixtures are the impure substances, made up of two or more physically mixed substances and not in the fixed ratio. Compounds are the pure form, made up of two or more chemically mixed elements and in a fixed ratio. Mixtures can be homogenous or heterogeneous in nature, but compounds are generally homogenous.
274859
A heterogeneous mixture is a mixture of two or more chemical substances (elements or compounds), where the different components can be visually distinguished and easily separated by physical means. Examples include: mixtures of sand and water. mixtures of sand and iron filings.
