Answer:
A mixture can contain components in any proportions while a compound contains components in fixed proportions. All components in a mixture do not chemically react, while the components in a compound do react and their original properties are lost.

Answer:
The larger the value of the electronegativity, the greater the atom's strength to attract a bonding pair of electrons. ... Electronegativities give information about what will happen to the bonding pair of electrons when two atoms bond. A bond in which the electron pair is equally shared is called a nonpolar covalent bond.
