An iron block of unknown mass at 185°f is dropped into an insulated tank that contains 0.8 ft3 of water at 70°f. at the same time, a paddle wheel driven by a 100-w motor is activated to stir the water. thermal equilibrium is established after 10 min with a final temperature of 75°f
determine
a)the mass of iron block.
b)entropy generated during this process

Given the data below for the reaction, 2 a + 2 b + 4 c => d + e + 3 f, the reaction is fill in the [ ] order in a, fill in the [ ] order in b, fill in the [ ] order in c and fill in the [ ] order overall.
