A process by which one substance combines with a second substance is called?

• A. Solution
• B. Mixture
• C. Combination
• D. Absorption

Answer: (D)

When two substances join to form a single substance, you’re looking at a chemical combination. This means a chemical reaction occurs and a new compound is created, with properties different from the starting materials. Absorption, by contrast, is just taking one substance up into another medium and doesn’t require forming a new chemical bond. A solution is dissolving a solute in a solvent to make a homogeneous mixture, and a mixture is simply physically blending substances without a chemical change. So the term that best fits a process where substances chemically join to make a new substance is chemical combination.
