“Hetero” is a Greek word that way “different,” “genus” way “kind.”
In a heterogeneous mixture, substances are NOT same mixed. The components of this mixtures space noticeably different from one another.

Examples:Sand and also waterOil and also waterSalt and also pepper
If us take two samples native a mixture that sand and also water, the proportions the the contents in each sample will be different.
➤ compound is a pure substance made up of two or an ext elements an unified chemically. E.g. H2 + O = H2O (water).
➤ Particles lose their original properties. H2 (gas) + O (gas)= H2O (liquid)
➤ Compounds space homogeneous.
➤ Compounds can not be separated by physical method. Deserve to you separate hydrogen and oxygen from a glass that water?
➤ Every compound has its very own chemical formula. H2O (water), CO2 (carbon dioxide),
➤ Compounds have fixed composition by mass. H2O (2 atom of hydrogen and also one oxygen) = water. H2O2 (2 atoms of hydrogen and also two atom of oxygen) = hydrogen peroxide.
➤ A compound has a addressed melting suggest and boil point.
➤ Examples: water, carbon dioxide, sodium chloride etc.
➤ A mixture is no a pure substance, consisted of of two or more substances blended physically. E.g. NaCl (salt) + H2O (water) = saltwater.
➤ Particles retain their initial properties. Sand (solid)+ Water(liquid) = Sandwater (solid+liquid)
➤ Mixtures may be homogeneous or heterogeneous.
➤ Compounds deserve to be separated by physics method. You have the right to separate pebbles and water quickly from a pebble-water mixture.
➤ Mixtures have no chemistry formula.
➤ Compounds have actually not fixed composition by mass.Salt (less) + water = saltwaterSalt (more) + water = saltwater
➤ A mixture go not have a addressed melting point and boil point.
➤ Examples: air, lemonade, salad dressing, sand-water etc.
Identify each substance as a compound, an element, a heterogeneous mixture, or a homogeneous mixture.

Hints (to distinguish pure substance, element, compound, mixture, homogeneous mixture, heterogeneous mixture) :Decide even if it is a substance is chemically pure. Is that made of only one type of atom or molecule? If YES, the problem is either an element or a compound.Can it be separated into its elements, if YES, it is a link otherwise the is one element.If a problem is no chemically pure, it is either a heterogeneous mixture or a homogeneous mixture.If its composition is uniform throughout, the is a homogeneous mixture, otherwise that is a heterogeneous mixture.
