A sample of hexane (C6H14) has a mass of 0. 580 g. The sample is burned in a bomb calorimeter that has a mass of 1. 900 kg and a specific heat of 3. 21 J/giK. What amount of heat is produced during the combustion of hexane if the temperature of the calorimeter increases by 4. 542 K? Use q equals m C subscript p Delta T. 8. 46 kJ 16. 1 kJ 27. 7 kJ 47. 8 kJ.

Choose the more precise measurement. 26.4 cm or 8.39 cm

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
