  1. 2. a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions are measured to have lower pH values than basic or alkaline solutions.
  2. 6. a molecule or ion capable of either donating a proton, known as a Brønsted–Lowry acid, or, capable of forming a covalent bond with an electron pair.
  3. 7. a process that leads to the chemical transformation of one set of chemical substances to another.
  4. 8. there are three definitions in the common use of the word base, known as Arrhenius bases, Brønsted bases.
  5. 9. a special type of homogeneous mixture composed of two or more substances.
  6. 13. a substance that dissolves a solute, resulting in a solution.
  7. 14. an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a.

  1. 1. Ground substance is an amorphous gel-like substance in the extracellular space that contains all components of the extracellular matrix except for fibrous materials such as collagen and elastin. Ground substance is active in the development, movement, and proliferation of tissues, as well as their metabolism.
  2. 2. an article or substance that is manufactured or refined for sale.
  3. 3. the minimum quantity of energy which the reacting species must possess in order to undergo a specified reaction.
  4. 4. is the process of increasing the rate of a chemical reaction by adding a substance known as a. are not consumed in the reaction and remain unchanged after it.
  5. 5. a material made up of two or more different chemical substance/substances which are not chemically combined.
  6. 10. a special type of homogeneous mixture composed of two or more substances.
  7. 11. a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative.
  8. 12. the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of amino acid residues that form temporary bonds with the substrate and residues that catalyse a reaction of that substrate.
  9. 15. an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it.
