(c) If the evaporating basin is heated too strongly some of the solid decomposes to form a gas.
Explain how this strong heating would affect the value of the calculated solubility of
the solid.
(3)

The correct answer is "atomic weight".

The answer to your q it is d

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
