The total Problem Portfolio average it worth 10% of your course grade. The set of portfolio problems for each chapter is worth 10 points The portfolio problems are similar to questions that will be on examinations You may work on these problems alone or with other students taking the course Work carefully and get help from your instructor if you have questions of get "stuck" To receive full credit: 1) the portfolio problems for each chapter must be turned in on or before the date given in the lecture, 2) problem set-up and/or work must be shown in the space provided and 3) the answer must include. where appropriate, the correct unit(s) and correct number of significant figures. An· answer without set-up will receive credit Portfolio problems turned in after the date given in class will loose 2 points a day and will not be accepted after the next c?ass meeting. 1 Ethanol. C3H5OH, MM = 46.1 g/mo?e. is a popular alternative to hydrocarbon fuels Use the thermochemicals equation below to calculate the grams of ethanol that must be burned to provide 4082 kJ of heat. First find moles needed; then find the mass. C2H5OH(l) + 3 O2(g) rightarrow 2CO2(g) Delta H = -1235 kJ Show transcribed image text The total Problem Portfolio average it worth 10% of your course grade.
