Police brutality is an ugly term we don't want to hear. Unfortunately, it's part of the necessary and sometimes nasty business called policing. Fortunately, it rarely occurs. But when it does -- it's big news. I'm a sophomore in high school and we are in the process of writing a research paper.
Best Answer: Change of internal energy equals heat transferred to plus work done on the gas, i.e.: âU = Q + W = 300kJ - 350kJ = -50kJ. Source(s):est Answer: Change of internal energy equals heat transferred to plus work done on the gas, i.e.: âU = Q + W = 300kJ - 350kJ = -50kJ. Source(s):
(b) Use data from Appendix C to calculate the standard free-energy change for the reaction at 298 K. Is your prediction from part (a) correct? SolutionAnalyze: In part (a) we must predict the value for Î´ G Â° relative to that for Î´ H Â° on the basis of the balanced equation for the reaction.nswers: (a) 1 mol of H 2 (g) at 100 Â°C and 0.5 atm, (b) 1 mol of H 2 O(l) at 25 Â°C, (c) 1 mol of SO 2 (g) at STP, (d) 2 mol of NO 2 (g) at STP Practice ExerciseSolution. Analyze: We need to select the system in each pair that has the greater entropy.
