Explanation / Answer

8. The hydrogen bond is responsible for the surface tension of water.

9. Blood is considered as colloid as it contains many cell types (WBC and RBC) suspended in the plasma.

10. The rate of chemical reactions is affected by

i. Substrate concentrations

ii. Presence/absence of a catalyst

iii. Presence/absence of an inhibitor/activator

iv. Temperature and pressure

11. The pH scale measures the H+ ion concentration in a solution.

pH = -log [H+]

12. A pH of 2 is considered acidic.

13. When the pH of a solution rises, the buffer will absorb protons.

14. Organic compounds contain carbon in combination with hydrogen and oxygen.
