Consider the lattice energy of any ionic compound. what combination of ions and charges will produce the largest (in magnitude) lattice energies? a. small ions and small charges b. large ions and large charges c. small ions and large charges d. large ions and small charges

c. small ions and large charges

Explanation:

The lattice energy is a consequence of the electrostatic interaction between the ions. Coulomb force, is the force that drives this electrostatic interaction and is defined by the equation below:

Q1 and Q2 are the charges of the ions and r is the distance between them. This means the the higher the charges and the smaller the distance (ionic radius), the stronger the force between ions and, therefore, the larger the lattice energy.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
