differentiate between mixture and compound???
Answers
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound.
There are four types of compounds, depending on how the constituent atoms are held together:
molecules held together by covalent bonds
ionic compounds held together by ionic bonds
intermetallic compounds held together by metallic bonds
certain complexes held together by coordinate covalent bonds.
A chemical formula specifies the number of atoms of each element in a compound molecule, using the standard abbreviations for the chemical elements and numerical subscripts. For example, a water molecule has formula H2O indicating two hydrogen atoms bonded to one oxygen atom. Many chemical compounds have a unique CAS number identifier assigned by the Chemical Abstracts Service. Globally, more than 350,000 chemical compounds (including mixtures of chemicals) have been registered for production and use.[1]

Answer:
mixture
- elements of compounds just mixed together to form a mixtures and No new compound is formed.
- a mixture has a variable composition.
- a mixture source the properties of the constituent substance.
- the constituents can be separated fairly easily by physical methods.
compound
- elements react to form New compounds.
- the composition of each new substance is always fixed.
- the new substances totally different properties.
- the constituent can be separated only by chemical for electrochemical reaction.
