2. Chemistry is the rational and empirical study of the structure of matter in natural processes and in planed experiments1.

4. Atoms is the smallest particle of an that has the chemical characteristics of that element4. The atom is composed of inner structures called electrons, protons, and neutrons.

5. Elements is a substance which cannot e decomposed or separated into simpler substances by chemical means, or a pure substances that contain only one kind of atom5. Examples are hydrogen (H), nitrogen (N), iron (K), oxygen (O), antimony (Sb) and copper (Cu).

6. A molecule is defined as an electrically neutral group of at least two atoms in a definite arrangement held together by very strong (covalent) chemical bonds6. A molecule may consist of atoms of a single chemical element, as with oxygen (O2), or of different elements, as with water (H2O).

7. What is the difference between Inorganic and Organic Chemistry?

8. Inorganic Chemistry is the study of chemical elements of their compounds with the exception of carbon compounds while Organic Chemistry is the study of substances produces by living organisms7.

9. What are the three (3) types of Carbohyrates? Provide a graphical presentation of each.

11. 4a.2. Fructose (Fruit Sugar/ Levulose)- a very sweet sugar found in all sweet fruits, leaves, roots of plants and honey and used as preserative for food stuffs, and as an introvenous nutrient.

12. 4a.3. Galactose – a sugar derived from the milk (lactose).4b. DISSACCHARIDES – double sugar; the monosaccharide bonded together; principle sugar transported throughout the bodies of land plants. 4b.1. Lactose (Milk Sugar) – glucose + galactose. Lactoseis a sugar that provide energy for growing infants. It is found in human milk, and also in cow’s milk and dairy products. Lactose is broken down during digestion by an enzyme called lactase. Some adults can’t make the enzyme lactase and so cannot digest the lactose found in the milk.
