Value: 3

Beast manages to get Rogue out of the lab and starts the experiment all over. He is following the qual scheme this time and has just added the H2SO4 to the Brown Ring Test when Arch-Angel comes into the lab. Arch-Angel is complaining about constantly having to switch between being blue with metal wings and pale with feather wings. Beast is so disturbed by the thought that anyone wouldn't prefer to be blue that he accidently shakes the test tube he performing the brown ring test in. He looks and the test tube and sees no rings.
a. He can conclude NO3- is present in the unknown because you are supposed to mix the reagents in the brown ring test anyway.
b. He can conclude NO3- is not present in the unknown because you are supposed to mix the reagents in the brown ring test anyway.
c. He can conclude NO3- is present because shaking won't affect his results.
d. He can conclude NO3- is not present because shaking won't affect his results.
e. He cannot conclude anything because Fe(SO4)NO is unstable and will disappear if the test tube is shaken.
f. The Beast should seek out a more drama free group of friends.
