Miguel Paulo D. Valdez BS Chem-3 EXPERIMENT 14- Heat Effects and Calorimetry Objective/ Introduction: Heat is a form of energy‚ sometimes called thermal energy‚ which can pass spontaneously from an object at a high temperature to an object at a lower temperature. If the two objects are in contact‚ they will‚ given sufficient time‚ both reach the same temperature. Heat always travels from hot to cold objects and two objects will reach an equilibrium temperature. Heat flow is commonly measured

The graph above shows the fish population on the Y (axis) and the dissolved oxygen on the X (axis). The fish population increases in the above graph due to more dissolved oxygen that is found in the body of water. For example: There is 0 dissolved oxygen (ppm) in the water‚ so there is 0 fish observed. The graph above shows the fish population on the Y (axis) and the dissolved oxygen on the X (axis). The fish population increases in the above graph due to more dissolved oxygen that is found in the

ENERGY RESERVES OF MACROMOLECULES SUMMARY This experiment was conducted in order to show the energy received from the food that humans eat on a daily basis. The energy that is required by the human body to perform chemical reactions is obtained from the chemical bonds that formed between the atoms in the molecules. To calculate the amount energy‚ types of food products were burned underneath a test-tube filled with water. The temperature rise gave an estimate of the energy released per gram.

Priya Chauhan August 27‚ 2012 Period 3 Rainbow Lab Objectives: We should develop skills measuring chemicals with a graduated cylinder. We should practice using the metric system. We should have the ability to follow directions and to test precision. We should practice lab safety procedures. Procedures: Part 1: Label six tubes in order: A‚ B‚ C‚ D‚ E‚ and F. Fill a beaker half way with water. Use it to rinse your graduated cylinder and test tubes. The second beaker is for

Which was the most important and least important factor in the outbreak of the First World War? In my opinion‚ the most important cause of the First World War was the Alliance System. By 1914‚ the main powers in Europe had been divided into two groups. These were: The Triple Alliance – Germany‚ Austria-Hungary and Italy‚

I agree Germany were aggressive but their actions were not completely responsible for the outbreak of war‚ there were other causes for the war which Germany were not responsible for‚ such as the Triple of Entente where Germany felt isolated and insecure. However‚ the Schlieffen Plan of 1905 referred to in sources 1 and 2 is frequently seen as an act of aggression. In source 1 Corrigan says that “Germany had in place a plan for an aggressive war” because they were concerned of having to fight Russia

Enzymes are generally protein macromolecules that act as catalysts in metabolic reactions. A catalyst is a chemical agent that speeds up a reaction without being consumed by the reaction. Enzymes speed up metabolic reaction rates by lowering the activation energy barrier‚ which is the amount of energy initially needed to spark a reaction. It allows reactant molecules to absorb enough energy to break bonds and react without raising the temperature to an extreme. During this process the substrate
