What is polarity? and i need an example on it

Polarity is the dipole-dipole intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule

An example is H2+ (SO4)2- in Tetraoxosulphate (VI) Acid

Explanation:

In the acid H2SO4, ionization results in the formation of a Positively charged hydrogen ion (2H+) and a negatively charged Sulphate ion (SO4)2-

The slightly positive and negative parts in the ACID generates the DIPOLE (two poles) and THUS explains polarity

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

the dependant variable is spilled water

the independent is the heat
