Balance the following equation. FeCl3 + MgO ---> Fe2O3 + MgCl2
Answer 1) Balance the Chlorine (Cl) (note that 2 x 3 = 3 x 2): 2FeCl3 + MgO ---> Fe2O3 + 3MgCl2 The Iron (Fe) also gets balanced in this step. 2) Pick either the Oxygen (O) or the Magnesium (Mg) to balance next: 2FeCl3 + 3MgO ---> Fe2O3 + 3MgCl2 The other element (Mg or O, depending on which one you picked) also gets balanced in this step.
Define the process of Diffusion.
Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration.
State two enzymes that function in protein digestion and describe the role of each.
Protein digestion occurs by means of enzymes. Two of these enzymes are, Pepsin and Trypsin. Pepsin: Pepsin functions in the stomach and breaks down large protein molecules into smaller polypetides. Trypsin: Trypsin functions in the lumen of the small intestine and breaks down large polypetide chains into smaller polypeptides.
