Asample of sno2 has a mass of 23.2 g. the masses of sn and in the sample are link to periodic table of the elements 11.6 g of sn and 11.6 g of o 7.7 g of sn and 15.5g of o 20.4 g of sn and 2.8 g of o 18.3 g sn and 4930

i think its 100

i hope this !

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.
