Process of Digestion and Absorption after eating a hamburger. After someone eats a hamburger with the works‚ they do not really think of what nutrients are in that hamburger‚ what the body does to get those nutrients out of the food‚ or even what process is used‚ they just think of how good it tasted. To get all the nutrients out of the food the human body uses processes called absorption and digestion. Some of the processes of digestion are mechanical and chemical; these are the step before the

9/23/2014 Experiment # 3 Purpose: the purpose of this experiment was to explore the distinctions between physical and chemical properties and between physical and chemical changes. Lab questions: 1. Based on my observation CaCl2 is soluble in water. 2. When 15% of HCl was added to CaCl2 as the teacher was performing the experiment I observed and realized some changes took place physically. It was physical change because the color was clear. 3. By adding 15% of HCl of CaCo3 ‚ made it change chemically
