FR 5. (15 points) Two blocks one of aluminum (Al MM= 26.98g/mol , Cp,m=24.35 J/mol K),...
8) A block of copper (Cp,m = 24.44 J K-1 mol-1 ) of mass 2.00 kg at 0 ℃ is introduced into an insulated container in which there is 1.00 mol H2O(g) at 100 ℃ and 1.00 atm. Assuming that all the vapour is condensed to liquid water, determine: (a) the final temperature of the system; (b) the heat transferred to the copper block; and (c) the entropy change of the water, the copper block, and the total system. >>...
5. Two 1.00 g blocks absorb 1.00 J of heat each. One block is made of gold (Au), and the other one of silver (Ag). How are the changes in their temperature ∆T(Au) and ∆T(Ag) related, and why? Cs(Au) = 0.128 J/(g·◦C), Cs(Ag) = 0.235 J/(g·◦C). (A) ∆T(Au) = 1.84∆T(Ag) because Cs(Ag) = 1.84Cs(Au) (B) ∆T(Au) = 1.84∆T(Ag) because Cs(Au) = 1.84Cs(Ag) (C) ∆T(Ag) = 1.84∆T(Au) because Cs(Ag) = 1.84Cs(Au) (D) ∆T(Ag) = 1.84∆T(Au) because Cs(Au) = 1.84Cs(Ag) (E) ∆T(Au)...

Based on the document below, 1. Describe the hypothesis Chaudhuri et al ids attempting to evaluate; in other words, what is the goal of this paper? Why is he writing it? 2. Does the data presented in the paper support the hypothesis stated in the introduction? Explain. 3.According to Chaudhuri, what is the potential role of thew alkaline phosphatase in the cleanup of industrial waste.
