Explanation:
Answer:
polymerization
Explanation:
Student is explaining the process of formation of a polymer and the process is called polymerization.
Polymer is made up of joining repeating units. The repeating units are called monomers.
Properties of the polymer is determined by the structure of monomer molecule.
For example, consider a well-known polymer Teflon.is made by the polymerization of tetrafluoroethane.
Thus, the student is explaining polymerization.
You can eliminate A, C, and D almost instantly if you know that engineers are construction workers. The answer is B.
Answer:
When a solution is heated, the solvent evaporates, leaving behind the dissolved solids as residue. When a solution containing dissolved solutes is heated, the solvent will evaporate.
Explanation:
. P.S. Evaporation to dryness cannot be use for solutions like sugar solution because the sugar will decompose upon heating.
