Asample 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 mc017-1.jpg. 8.46 kj 16.1 kj 27.7 kj 47.8 kj

The reaction: (ch3)3cbr + oh− → (ch3)3coh + br− in a certain solvent is first order with respect to oh−. in several experiments, the rate constant k was determined at different temperatures. a plot of ln(k) vs 1/t was constructed and the slope of the line was -1.10 x 104 k with a y-intercept of 33.5. what is the value for k at a temperature of 25°c?
