Imagine a drop of oil in water. if you add a surfactant, explain how the surfactant molecules organize themselves around the oil drop.

Explanation:

Surfactant are the substances that help in reducing the surface tension between two liquids. These liquids can be either a gas and a liquid or a liquid and a solid.

Therefore, when a surfactant is added to a mixture of oil and water then hydrophilic molecules of surfactant will surround the water molecules whereas hydrophobic molecules will surround the oil molecules.

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.
