Pellets of calcium chloride are spread on a sidewalk covered in water that is 36°c. under which circumstance will the calcium chloride dissolve faster?

In case if the pellets of the calcium chloride gets crushed.

Explanation:

When the pellets of calcium chloride get crushed it enhances the surface area of the compound. With the increase in surface area, the number of collisions in between the molecules of reactants increases. In the given case, the reactant molecules are water molecules and calcium chloride ions. In the procedure of dissolution, the calcium chloride ions get hydrated by the water molecules dipoles. As the frequency of the collision enhances, the activation energy gets lowered in order to begin the reaction.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
