Equation given: 2AgNO3 + BaCl2 —> 2AgCl + Ba(NO3)2

2. If 57 g BaCl, is reacted, what mass of AgNO3 is needed?

3. If 125 moles of AgNO3 is reacted, how many grams of AgCl will be produced?

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.

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.
