Goodness, there are at least two mistakes in the pic:
a) There's clearly one curved arrow missing (breaking of the carbonyl double bond during formation of the tetrahedral intermediate) in the mechanism part.
b) I should have stuck with SOCl2 in the bottom half, that's how you'd get loss of SO2 in the formation of the acid chloride.

OP out.

Just checking if I was wrong or not, it just seemed too simple for that to be the answer.. Thanks though

Everyone probably already knows this one.

xSO4 is an anhydrous salt.

How do you work out the "x" is xSO4 when the "mass concentration" of xSO4 is 120.5g/mol?

Is it simply that I work out that SO4 is 96.1g/mol and then do 120.5 - 96.1 = 24.4 = Mg?

Thanks in advance, Also, in a kind of thank you, I will be posting the addresses of helpful sites for maths and science etc. I suppose a lot of you may know of them already.

I see OPs logic. It does make sense

I agree with OP he is my idol
1000000 internets to you sir

My science proffesor taught me this you morons. he is obviously smarter than you

A 'snooker' table (measuring 8 metres by 4m) with 4 'pockets' (measuring 0.5m and placed at diagonal slants in all 4 corners) contains 10 balls (each with a diameter of 0.25m) placed at the following coords:
2m,1m...(white ball)
...and red balls...
1m,5m... 2m,5m... 3m,5m
1m,6m... 2m,6m... 3m,6m
1m,7m... 2m,7m... 3m,7m

The white ball is then shot at a particular angle from 0 to 360 degrees (0 being north, and going clockwise).
Just to make it clear, a ball is 'potted' if at least half of the ball is in area of the 'pocket'

Assuming the balls travel indefinitely (i.e. no loss of energy via friction, air resistance or collisions), answer the following:

a: What exact angle/s should you choose to ensure that all the balls are potted the quickest?

b: What is the minimum amount of contacts the balls can make with each other before they are all knocked in?

c: Same as b, except that each ball - just before it is knocked in - must not have hit the white ball on its previous contact (must be a red instead of course).

d: What proportion of angles will leave the white ball the last on the table to be potted?

i have a theory:

my dick belongs in your mouth to shut you up.

radioactive transporter. already offered...

I was a christian until I was old enough to realize that it was all bullshit. I actually read the bible more frequently (not particularly frequently) now that I am an atheist though. /trolled

>The Bible makes no specific claims that absolutely conflict with science and can be disproven.
Almost made me rage there. lol

Best thread on /sci/.

>Is it possible to reconcile theories of the universe and evolution with a liberal interpretation of Christianity?

Yes. You need a very liberal interpretation... like one that ignores the majority of Christianity.

i hope you don't think those all do the same thing
