What is the process of dissociation? A. A solvent separates the individual molecules in a compound and carries them away, but leaves them chemically unchanged.
B. A solvent separates the atoms of a covalent molecule and carries them away, breaking the substance down into individual ions.
C. A solvent disrupts the lattice-like structure of an ionic compound, causing the ions to combine into a new compound.
D. A solvent disrupts the lattice-like structure of an ionic compound, breaking the compound into individual ions.

Option D. A solvent disrupts the lattice-like structure of an ionic compound, breaking the compound into individual ions.

Explanation:

Dissociation of compound simply involves the splitting of ionic compounds into the individual ions that make up the compound. This can be seen when an acid dissolves in water as illustrated below:

In this case we shall use H2SO4.

H2SO4(aq) <==> 2H^+ + SO4^2-

From the above illustration, we can see that the solvent (water) breaks the acid into the individual ions that makes up the acid.

explanation:

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
