The balanced chemical equation for the reaction of copper (Cu) and silver nitrate (AgNO3) is shown
below.
Cu + 2AgNO3 + 2Ag + Cu(NO3)2
How many moles of copper must react to form
0.854 mol Ag?
mol Cu

to make a supersaturated solution, make a saturated solution of sugar by adding 360 grams of sugar to 100 ml of water at 80 degrees celsius. when the water cools back down to 25 degrees, that 360 grams of sugar will still be dissolved even though the water should only dissolve 210 grams of sugar.

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.
