Which of the following processes would you predict to have a positive value for `Delta"Sº"_"reaction"` ? A.
2SO2(g) + O2(g) → 2 SO3(g)

B.
P4O10(s) + 6H2O(l) → 4H3PO4(s)

C.
2POCl3(g) → 2PCl3(g) + O2(g)

D.
2H2(g) + O2(g) → 2H2O(l)

answer; i believe the correct answer is (solid gold);

i'm pretty sure it is letter c.) car

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
