Because of its bonds Ionic bonds are very strong - a lot of energy is needed to break them. So ionic compounds have high melting and boiling points.

An ionic compound is arranged in a organised lattice structre that allows for the greatest electrostatic attraction between the opposite charged atoms and the lesser electrostatic repulsion between the same atoms, where the atoms are as closely packed as possible. So the amount of energy (in form of heat) needed to break the electrostatic attraction between the atoms, so this means that ionic compounds have very high melting points.

classify each of the following as a pure substance or a mixture. if it is a mixture is it homogenous sea water ice cubes lemonda

KATRIN_1 [288]

Pure substance - Ice cubes

Mixture - Homogenous sea water , lemonade

Pure substance are the substance which have constant chemical composition and characteristic.

Mixture is material made up of two or more chemical substance which are not chemical bonded. These materials in mixture are not in definite proportion.

As water ice cubes has only water in it thus it is pure substance.

Homogeneous sea water contains various salts and impurities in it thus it is mixture.

Lemonade contains lemon juice and water in it . Thus, it is mixture.
