Introduction In this lab I observed the burning of a candle very closely. I found out that the candle needs oxygen to burn‚ that it produces carbon dioxide similar to the way that my body produces carbon dioxide‚ and that a candle produces water as a second waste product. I learned that if I hold an object in the flame it becomes covered with soot which is unburned carbon fuel. Finally‚ I learned that neither the solid wax‚ nor the melted wax‚ nor the wick burns when a candle is lit. In fact‚ the

which alpha glucose is stored as. A polysaccharide is a long chain of monosaccharaides joined together by glysocidic bonds. Glysocidic bonds are covalent bonds that join a carbohydrate molecule to another group. These bonds are formed during a condensation reaction when two hydrogen atoms and one oxygen atom is removed as

Exothermic vs Endothermic Worksheet 1. Change 1. When calcium carbonate forms calcium oxide and carbon dioxide heat is absorbed. Change 2. Calcium oxide releases heat when shaken with carbon dioxide. Which line BEST describes these changes? 1. change 1 is exothermic; change 2 is endothermic 2. change 1 is endothermic; change 2 is endothermic 3. change 1 is exothermic; change 2 is exothermic 4. change 1 is endothermic; change 2 is exothermic 2.

sulfuric acid (H2SO4)‚ chloric acid (HClO3)‚ hydrobromic acid (HBr)‚ and the most famous of all‚ hydrochloric acid (HCl). The required physical state of the reaction between the two phenol groups and the acetone group in order to produce BPA is condensation‚ the opposite of evaporation. Therefore‚ the chemical structure and shape of bisphenol A cannot be perceived unless there were two phenol groups‚ one acetone group‚ and an effective

* Large molecules sometimes composed of a large number of repeating subunits * Four major classes: Carbohydrates (made of simple sugar/glucose)‚ Lipids (Glycerol and Fatty Acids)‚ Proteins (Amino Acids) and Nucleic Acids (Nucleotides) * Condensation reaction/dehydration synthesis: a reaction that creates a covalent bond between two interacting subunits. Removal of H from one functional group and an OH from the other‚ and the H come together to form a water molecule (H2O). Anabolic process
