Experiment A1: Kinetics of the Reaction between Acetone and Iodine The key aim of this experiment was to determine the rate equation for the acid-catalysed iodination of acetone and to hence consider the insinuations of the mechanism of the rate equation obtained. The stoichiometric equation for the reaction between iodine and acetone is below‚ followed by the rate equation (where x‚y‚z and k are the values to be obtained): I2 + CH3COCH3 CH3COCH2I + HI -d[I2]/dt = k [I2]x [CH3COCH3]y [H+]z

3.3 Cycles of Matter Recycling in the Biosphere Unlike the one-way flow of energy‚ matter is recycled within and between ecosystems Elements‚ chemical compounds and other matter are passed from one organism to another and from one part of the biosphere to another through biochemical cycles It connects biological‚ geological and chemical aspects of the biosphere Matter can cycle through biosphere because biological system do not use up matter; they transform Uses same molecules again and again

Sam Wood‚ a respected police officer in Wells‚ South Carolina‚ patrols the city every night. One night‚ after stopping at his usual diner for a snack‚ and discussing Negros unfavorably with Ralph‚ the night counterman‚ Sam finds a body in the middle of the highway. He reports the body‚ which is soon tentatively identified as that of Maestro Enrico Mantoli‚ the conductor and lead organizer of the city’s upcoming music festival. Bill Gillespie‚ the chief of police‚ is notified‚ and after his arrival

Heat Stress in the Work Place! Eastern Kentucky University Heat Stress is the exposure to extreme heat or working in hot environments. Workers who are exposed to this may be at risk of heat stress. Heat Stress can result in occupational illnesses and injuries. “Heat stress can result in heat stroke‚ heat exhaustion‚ heat cramps‚ or heat rashes. Heat can also increase the risk of injuries in workers as it may result in sweaty palms‚ fogged-up safety glasses‚ and dizziness. Burns may

Laboratory III: Forces Problem IV: Normal and Kinetic Frictional Force I John Greavu March 13‚ 2013 Physics 1301W‚ Professor: Evan Frodermann‚ TA: Mark Pepin Abstract The dependence of two-dimensional velocity and position components on time as well as whether or not said components are constant was determined. Video was recorded of a ball being projected laterally and data of its flight were plotted. From analyzing the data and the corresponding graphs that followed‚ it was shown that while the

Rearranging gives Heat and Temperature Change: Specific Heat Capacity Q = mc T 4186 J = 1 kcal Ex: If 15 kcal of heat are added to 5.0 kg of silver‚ by how much will its temperature rise? Ex: An aluminum cup having a mass of 250.0 g is filled with 50.0 g of water. The initial temperature of the cup and water is 25.0 °C. A 75.0-g piece of iron initially at 350.0 °C is dropped into the water. What is the final equilibrium temperature of the system assuming that no heat is lost to the
