im failing my 10th grade chem class.. can someone help and explain this to me?
heres a question from my textbook. i've read the chapter but dont understand it at all.
what quantity of energy is released when 506g of liquid water freezes?
what mass of steam is required to release 4.79 X 10<sup>5</sup> kJ of energy on condensation?
for the vaporization reaction Br<sub>2</sub>(l) yields Br<sub>2</sub>, delta H<sup>0</sup> =31.0kJ/mol and delta S<sup>0</sup> = 93.0 J/(mol*K). at what temperature will this process be spontaneous?
i would really appreciate answers to all of these, so i can be able to do it myself. this is pretty much all that my tests/quizes/ homework consist of.
