3 points A chemist mixed two substances together: a red solid with no smell and
colorless gas with a sharp smell. Their repeating groups of atoms are
shown above on the left. After they were mixed, the chemist analyzed the
results and found two substances. Is any ending substance the same
as the red solid?--- What happened to the atoms of the starting
substances as the ending substances formed? --- Is this model correct in
explaining the full chemical reaction? Why or why not? Be sure to explain
your answers to all three parts. *

you didnt put any of the following

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

cu2o

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.
