Calculate the heat in kJ released during the combustion of Unknown # 1. Mass = 9.7574
Initial Temp = 22 Celsius
Max temp = 276.1 Celsius
DetaT = 254.1 Celsius

answer: your mm

explanation:

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
