How does the composition of a pure compound differ from that of a mixture?

Answer 1

A compound consists of two or more elements that have physically reacted and bonded together, either ionically ar covalently. An example of this is water - H2O. A mixture, on the other hand, is two or more substance that have been brought together, but have not chemically bonded with each other.

Answer 2

A compound doesn't show the properties of its constituent elements; where as a mixture does.

A mixture mostly can be separated by some physical means; where as compound is difficult to separate.

Answer 3

Mixtures

• A mixture the product of a physical combination of two or more substances
• The composition of a mixture is variable.
• Each of its components retains its characteristic properties.
• Its components are easily separated.

Compounds

• A compound is the product of a chemical reaction involving constituent elements and/or compounds
• The relative proportions of the elements in a compound are fixed.
• The components of a compound do not retain their individual properties. Both sodium and chlorine are poisonous; their compound, table salt - NaCl - is absolutely essential to life.
• It takes large inputs of energy to separate the components of a compound.

Answer 4

A pure compound is made up of a fixed ratio of elements, whereas a mixture consists of two or more substances physically combined without fixed ratios. Pure compounds have consistent properties throughout, while mixtures can vary in composition and properties depending on the ratios of their components.

Answer 5

A pure compound is made up entirely of one substance that has a single chemical property. A mixture is made up of two or more pure compounds with distinct chemical properties.
