) A rigid tank initially contains 5 kg nitrogen (N2) at 500 kPa and 327 oC. N2 is gradually cooled to 27 oC. due to the heat loss from N2 to ambient air at 20 oC, which is considered as boundary temperature of heat transfer. (5a). (4p) Please calculate the change in the total entropy of N2 during this cooling process (5b). (3p) Please find the heat loss from tank to ambient air during this process. (5c). (3p) Please determine the entropy generation during this process. (5d). (2p) Is this process reversible, irreversible or impossible

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant

For the reaction shown, find the limiting reactant for each of the following initial amounts of reactants. 4al(s)+3o2(g)→2al2o3(s) a) 1 molal, 1 mol o2 b) 4 molal, 2.6 mol o2 c) 16 molal, 13 mol o2 d) 7.4 molal, 6.5 mol o2
