List the salts in order from weakest to strongest lattice energy (most positive to most negative). magnesium chloride, barium chloride, calcium chloride, strontium chloride Group of answer choices magnesium chloride < calcium chloride < strontium chloride < barium chloride calcium chloride < barium chloride < magnesium chloride < strontium chloride magnesium chloride < barium chloride < calcium chloride < strontium chloride strontium chloride < calcium chloride < barium chloride < magnesium chloride barium chloride < strontium chloride < magnesium chloride < calcium chloride barium chloride < strontium chloride < calcium chloride < magnesium chloride calcium chloride < magnesium chloride < strontium chloride < barium chloride

The correct order from weakest to strongest lattice energy is;

Option B; barium chloride < strontium chloride < calcium chloride < magnesium chloride

     The lattice energy is defined as the energy required to dissociate one mole of an ionic compound to its constituent gaseous ions.

      Now, Lattice energy is inversely proportional to the size of the ions. This implies that as the size of the ions increases, then the lattice energy will decrease. The size of the ions is also called the atomic radii.

Thus, as atomic radii increases, lattice energy will decrease.

Now, the compounds we are dealing with are;

Barium chloride

Strontium Chloride

Calcium Chloride

Magnesium Chloride

      All the metals that form the chlorides above are all in group 2 of the periodic table and in chemistry,  atomic radius decreases across a period and increases down a group.

     Thus, the order of increasing atomic radii down the group 2 are;

Magnesium, Calcium, Strontium, Barium.

Since barium is farthest down the group, it will have highest atomic radius and thus weakest lattice energy while magnesium will have the smallest atomic radius and strongest lattice energy.

      In conclusion, the order from weakest to strongest lattice energy is;

barium chloride < strontium chloride < calcium chloride < magnesium chloride

The order of increasing lattice energy from weakest to strongest is;

Barium chloride < strontium chloride < calcium chloride < magnesium chloride.

The lattice energy of a solid refers to the energy released when the crystal lattice of an ionic compound is formed. The lattice energy depends on the ionic size of the ions. The smaller the ions that form the compound the greater its lattice energy.

Based on this, the order from weakest to strongest lattice energy is;

Barium chloride < strontium chloride < calcium chloride < magnesium chloride. We can observe that the lattice energy increases as the size of the cation decreases since the size of the anion is held constant.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
