Document Summary

A 12. 8 g sample of ethanol (c2h5oh) is burned in a bomb calorimeter with a heat capacity of 5. 65 kj/ c. Using the information below, determine the final temperature of the calorimeter if the initial temperature is 25. 0 c. The molar mass of ethanol is 46. 07 g/mol. Rh = -1235 kj/mol: 53 c, 28 c, 111 c, 86 c, 74 c, oxygen gas at 34. 5 c expands from 45. 7 l to 74. 5 l against a constant pressure of 1. 00 bar. What is the work done, in joules, by the system: -9. 93 104 j, -2. 88 103 j, 2. 88 103 j, 7. 45 103 j, 9. 93 104 j, what is the reaction that corresponds to. 3clo (aq) + h+(aq) hclo3(aq) o fh for chloric acid, hclo3(aq): hclo3(aq) + h2o(l) , h(g) + cl(g) + 3 o(g) hclo3(aq) 2 o2(g) hclo3(aq: h2(g) + cl2(g) + 3, h2(aq) + cl2(aq) + 3 o2(aq) 2 hclo3(aq)
