A 1.800-g sample of phenol 1C6H5OH2 was burned in a bomb calorimeter whose total heat capacity is 11.66 kJ/°C. The temperature of the calorimeter plus contents increased from 21.36 to 26.37 °C.
(a) Write a balanced chemical equation for the bomb calorimeter reaction. (b) What is the heat of combustion per gram of phenol? Per mole of phenol?
Biology Lecture Notes Chapter 6 The Energy of Life ● The living cell is a miniature chemical factory where thousands of reactions occur. ● The cell extracts energy and applies energy to perform work. An Organism’s Metabolism Transforms Matter and Energy ● Metabolism is the totality of an organism's chemical reactions. ● Metabolism is an emergent property of life that arises from interactions between molecules within the cell. Metabolic Pathway A metabolic pathway begins with a specific molecule and ends with a product. ● Each step is catalyzed by a specific enzyme. ● Catabolic pathways release energy by breaking down complex molecules into simpler compounds. ● One example of catabolism is cellular respiration. ● Anabolic pathways consume energy to build complex molecules from simpler ones. ● One example of an anabolic pathway is photosynthesis. Energy Kinetic Energy is energy associated with motion. Potential Energy is energy that that possesses because of its location or structure. Thermal energy is kinetic energy associated with random movement of atoms or molecules. ● Heat is thermal energy in transfer from one object to another. Light is another type of energy that can be harnessed to perform work. Chemical energy is potential energy available for release in a chemical reaction. If energy always equals “100” assign a value for kinetic and potential energy for “W”, “X”, “Y”, and “Z”. The Fir
