Which one of the following ionic solids would have the largest lattice energy?

CaBr2

CsI

CaCl2

NaCl

NaF

Answers

Answer 1

Answer:

CaCl2

Explanation:

Answer 2

The ionic solid CaCl₂ would have the largest lattice energy. Therefore, option (c) is correct.

What is the lattice energy?

Lattice energy is the heat of formation when one mole of crystalline ionic solid is generated from its constituent ions in their gaseous state.

For example, the lattice energy of sodium chloride crystal is the energy change of reaction when Na⁺ and Cl⁻ ions react to produce a NaCl crystal, which is equal to -786 kJ/mol.

The relation between lattice energy and lattice enthalpy at constant pressure is given by:

ΔU (lattice) = ΔH (lattice) - PΔV

Lattice energy is directly proportional to the charge on ions and inversely proportional to the interionic distance between ions.

For NaCl and NaF the charge on the ions is +1 and -1 while the size of the ions is small. So they have less lattice energy.

CsI ionic solid have a larger size of ions Cs⁺ and I⁻. So CsI will have less lattice energy. CsBr₂ has +2 charge on calcium but the size of both ios is larger. So, CsBr₂ will have less lattice energy.

CaCl₂ has + 2 charge on calcium as well as the ionic radius is also samll. Therefore, CaCl₂ would have the largest lattice energy.

2. Which property is a property of water? (Choose all that apply
Cohesion
Relatively high boiling point
High surface tension
Adhesion

Answers

Answer:

cohesion and adhesion

Answer:

Cohesion, Adhesion, Relatively high boiling point, and high surface tension.

Explanation:

Cohesion and adhesion give water molecules their 'stickiness' for each other and other molecules/surfaces, and high surface tension is why things like feathers can 'float' on the surface of water.
