Answer

Brief Explanations:

  • For the first question, soap has a hydrophilic (water - loving) and a hydrophobic (grease - loving) end. It bonds with grease to remove it during cleaning.
  • For the second question, food spoilage odors are caused by chemical changes due to bacteria or mold growth.
  • For the third question, bleach contains strong oxidizing agents that break down stains chemically.

Answer:

  1. B. Bonds with grease
  2. C. Chemical changes from bacteria or mold
  3. B. Breaks them down chemically
