Explanation:

A 48-yr-old female patient presented to our hospital’s emergency department with burns in the left wrist. The lady had an ongoing problem of chronic wrist pain on the affected side. The night of the injury she had been using an ancient home remedy allegedly passed down from one generation to the next. This consisted of a concoction of coal ash, water, salt, and olive oil, which had to be turned into a paste and applied locally with the help of a bandage over the painful area.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
