What. I dont see answers. Uh oh i should get the metal doors ready
Man bro, i thought Nevada was insane, this is a whole new level.
I disagree, it should be π and I can say that will 100% certainty. arccos(cos (2π/3)) + arccos(cos (5π/3)) = π arccos is the cos-1() button on your calculator so change your calc to rads and type that in, you will get π
arcos(cos 2pi/3) + arcos(cos 5pi/3) = pi or 180 degrees or 3.14159

79.0J/K- 21600/298k= +6.5
Could I just use the formula DSuniv= DSsys- (DHsys/T)
I did as you said and I got the wrong answer. the correct asnwer is supposed to be +6.5, and I am getting -25.8.. Can you just show me how to do it with numbers and steps. I am just more confused now.
I.e Pb(NO3)2+NaI==> PbI2 + NaNO3 I know NO3 will dissolve in water, but if I didn't know if PbI2 was solid or aqueous, how would i figure that out? and Al(3+)+ 6F- ===> [AlF6]^3- (aq)
If I was taking an exam and I had no solubility rules given...

So since Delta S= +79.0J/K is Delta S equal to Delta Ssys? I don't get the relationship of Delta S and sys and surr with delta S (entropy) that would make it become +79.0J/K DSsys and then DSurrs= (-21600J/mol*1mol)/298K= -72.5J/K Suniv= +79.0J/K+-72.5J/K=
