What is the difference between compound and mixture?
Answer:
Compound:---
1) When two or more substances combine in a fixed ratio by mass, compounds are formed. e.g. In water(H2O) H:O = 1:8 will always be same.
2)These are pure.
3)They can not be separated into their constituents by simple methods.
4)The state of combining substances(constituents) r different from that of the compound.
Mixture:---
1) substances combine in any ratio e.g. air, soil, milk etc.
2) They are not pure.
3) Constituents can be seprated back easily from the mixture.
4) The physical states of constituents may or may not change after combining.
Compounds are chemically bonded, mixtures are not.
A compound is a combination of two or more elements to make a different molecule. A mixture is two or more distinct substances all swirling around each other (could be elements or compounds).
A compound always has the same proportions while a mixture can vary. For example Sodium Chloride always has one atom of sodium combined with one atom of chlorine to give you table salt (NaCl). A mixture might be one pound of salt to one pound of sugar. You could vary this ratio any way you like.
Mixture
A sample of matter composed of two or more substances, each of which retains its identity and properties.
Compound
A substance of two or more elements in fixed proportions. Compounds can be decomposed into their constituent elements.
A chemical compound is a chemical substance of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition. The ratio of each element is usually expressed by chemical formula. For example, water (H2O) is a compound consisting of two hydrogen atoms bonded to an oxygen atom. The atoms within a compound can be held together by a variety of interactions, ranging from covalent bonds to electrostatic forces in ionic bonds. A continuum of bond polarities exist between the purely covalent bond (as in H2) and ionic bonds. For example H2O is held together by polar covalent bonds. Sodium chloride is an example of an ionic compound.
In chemistry, a mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components. Some examples of Mixtures are oil, ocean water and soil. Mixtures are the product of a mechanical blending or mixing of chemical substances like elements and compounds, without chemical bonding or other chemical change, so that each ingredient substance retains its own chemical properties and makeup [1] . While there are no chemical changes in a mixture, physical properties of a mixture, such as its melting point, may differ from those of its components. Mixtures can usually be separated by mechanical means.
There are two different types of mixtures: homogeneous mixtures (including solutions, colloidal dispersions and suspensions), and heterogeneous mixtures.
Water is Compound of Hydrogen and Oxygen.The level is Atomic.
Nimbu Sharbat is a Mixture of Water , Lemon and Sugar. It cannot have Chemical formula like H2O.
NCP and Congress is a Compund.
UPA is a Mixture.
a compund can't be seperated by physical means a mixture can
The substance in a mixture are combined but not chemically changed. The compound is made up of more then one element. The elements in a compound have been chemically changed. Mixtures and compound are different in several ways. A mixture of iron and sulfur does not have chemical composition. The mixture might contain equal pats of each element. It also might have twice as much as sulfur. Each substance in the in a mixture of iron and sulfur keeps its own properties. A mixture of iron and sulfur can be separated by physical means. The compound iron sulfide always has a definite chemical composition. A molecule of iron sulfide always contains one part iron and one part sulfur. This because the elements in the compound have bee joined chemically each element losses its properties. So the iron and sulfur in iron sulfur cannot be separated physically.
A compound has completely different characteristics than its ingredients. Example: Water behaves quite differently than either Oxygen or Hydrogen.
A mixture will behave much like its ingredients. Example: Kool-aid. Water is still wet, still flows and freezes the same. The sugar is stll sweet and can easily be taken back from the water. Dye is still red, or yellow, or green, or whatever.
Compounds are atoms [or ions], which are chemically bonded.
Their properties are the properties of the compound and not of the atoms. E.g. Sodium would burn your tongue whereas sodium chloride tastes nice with chips
Mixtures can contain elements or compounds.
Their properties are the collective properties of the elements and compounds.
E.g. Iron is magnetic. Sulphur is not. Parts of a mixture of iron and sulphur are magnetic - the iron 'parts'.
E.g. Air. Contains oxygen, which allows fires to burn.
Contains carbon dioxide, making Earth warmer
