Ionic compounds take the form of three dimentional arrays by alternating anions and cations in order to minimize the potential energy of the system by maximizing the attractive force between opposite charges.

The resultant geometric structures are known as crystal lattices and their arrangements depend on the ion's sizes and, since they are bound though electrostatic attraction, their radius ratio.

I hope you find this information useful and interesting! Good luck!

What is the chemical name for the balanced equation? 2Al+3Pb(NO3)2=2Al(NO3)3+3Pb

Zigmanuir [339]

The chemical name for reactant side:

Al - Aluminium, Pb(NO3)2 - Lead(II) nitrate.

The chemical name for product side:

Al(NO3)3 - Aluminium nitrate, Pb - lead.

Explanation:

This is an oxidation-reduction (redox) reaction:

3 $Pb^{II}$ + 6 e- → 3 $Pb^{o}$ (reduction)

2 $Al^{o}$ - 6 e- → 2 $Al^{III}$ (oxidation)

Pb(NO3)2 is an oxidizing agent, Al is a reducing agent.

Reactants:

Al uminium

Names: Aluminum, Aluminium powder, Al

Appearance: Silvery-white-to-grey powder, Silvery-white,

malleable, ductile, odorless metal.

Pb(NO3)2 – Lead(II) nitrate

Other names: Lead nitrate, Plumbous nitrate, Lead dinitrate

Appearance: White colorless crystals, White or colorless crystals

Products:

Al(NO3)3 – Aluminium nitrate

Other names: Nitric Aluminum salt, Aluminum nitrate,

Aluminium(III) nitrate

Appearance: White crystals, solid | hygroscopic

Pb - lead

Names: Lead, Lead metal, Plumbum

Appearance: Bluish-white or silvery-grey solid in various forms.

Turns tarnished on exposure to air. A heavy, ductile,

soft, gray solid.
