Well it helps you with the final result.
If your answer turns out differently than the sign, you did something wrong.

That's sorta like my last resort.

Hess's law, I have no clue. I really am sorry. I just could never figure that out.

Out of everything else! Damn it.

I don't think I'll be much help.

Ironically enough, I am good at everything else but hess's law.

Are you allowed to use Bond Formation/Breaking tables?

If so, it's easy to calculate Delta H.

First, For the final reaction, see if the H is + or -

By seeing how many bonds are formed compared to how many bonds broken...

if more bonds are formed, then it will give off heat.
if more less bonds are broken, then it will require heat, aka Endothermic.

Try that.

I'll be back in a min.

It's valances are functional.

Are you fucking retarded?

It can expand its octet.

What the fuck?
Why a picture from Watership Down?

Sorry, nostalgia moment there!


OH and TAKE MY FRUSTRATION!

Don't be jelly of sum autistic kid who bases everything he knows into theories.

He won't make a living off of it. Only other retards think theory based sciences are beneficial.

Phenol and Benzaldehyde

I think

OP you're awesome.
Anyone who loves software engineering is a friend of mine!

These are awesome.

Why are you mother fuckers making this fucking retard into a celebrity like Justin Bieber?

IF WE DON'T GIVE HIM ATTENTION, HE WILL DIE.

He isn't smarter than any other person on /sci/, he is age doesn't surprise me.

He isn't going to be successful since he's all fucking theory.

I feel you OP.

I get nearly 20% on sigfigs to.
And get the answer right.

I don't understand it either.

I'm with this guy.

>>4411754
You sir are a fucking retard.
I believe you have a register to attend.

>>4411634
Are you legit?

That's Nikolai Tesla!

>>4411607
Wait why am I even giving advice, I never even had a fucking GF before.

Lmfao, I'm in the same boat as you.

>>4411583
Still better than getting all caught up in that social crap.
The lonelier you are, the smarted you'll become.
Wait till you can support someone who actually loves you for who you are, not just cause that girl will end up breaking up with you a few months after it starts.

If you love the Field of CS, don't ever EVER major in Java. A Minor is fine.
Java is to common, and not mainstream application based.
Stick to The C series. ie C# C++ or just C

Don't they have a school internet filter?

>Also pseudoimplying that you care why?

Tell them that they aren't smart enough to do anything practical in life.

>>4411561
Don't feel bad. It's not worth having a GF in HS. Take it from my experience.

I must agree with you there!
It was a huge portion of my childhood.

Lithium is used to treat people with bipolar disorder.

It burns on oxygen and produces a bright glow. So bright that you could get blind spots on your corneas if you stare to long.

It means there are 12 water molecules surrounding it,

It is in it's hydrous form.

Anhydrous is just KAl(SO4)2

It all depends on the outer valance electron pairs that cause hydrogen bonding.

>>4403354
Are you fucking serious?

You discredit me on the fact I'm a tripfag.

Come the fuck on!

If you think I'm trolling, you have me wrong. I read the same god damn article. I've been a subscriber for nearly 6 years now.

inb4 he dies of cancer.

I have a home lab, and even working with certain chemicals, I could get cancer. (I think I already have something gone wrong with me)
This kid has no clue. I think it's a bullshit story that Popsci made up to keep us buying.

Has anyone noticed how many fucking ads there are now in the magazine itself?
It's not even a credible magazine anymore.

I miss the old PopSci!

Astronomy is about as useful as Astrology.

Just saying.

Zundahl really has it all man.
I tell you this, I got an A+ on my exam, a 97, I was beaten by my best mate who got an 100.
We both set the curve for the whole class.
Fucking lol'd.
We both got 5's on the full out AP exam.
All because we basically did the problems in the book.
They seem so useless, but they prepare you well enough.

>>4390705
Look for Zundahl Chemistry 2nd ed.
Torrent it.

You'll learn a lot.
