A nuclear reactor produces an average of 2000MW of thermal energy annually. Compute the number of its fission events per year. Compute the mass of U235 to produce an average of 2000MW of thermal energy for a year. Compare the mass of the nuclear fuel with the equivalent mass of coal. If the nuclear power plant is replaced with a coal-fired power plant burning coal with 75% carbon, calculate the carbon and CO2 emissions per year. Assume Coal TEC

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask
