Question

give technical reasons for the following. 1. the process of mixing a solid liquid or gas uniformly with another substance to form a solution
2. the process by which a substance changes the from solid state to the gaseous state directly without forming the liquid state​

Answer 1

Answer:

Whether a given process, including formation of a solution, occurs spontaneously depends on whether the total energy of the system is lowered as a result. Enthalpy is only one of the contributing factors. A high ΔHsoln is usually an indication that the substance is not very soluble
