Step 1, 2, and 4 I get. Explain what the hell you're talking about in step 3.

From what I've been able to work out, I think that the formula of the solid product is UO2F2.

The balanced equation would go something like this: 2H2O + UF6 → 4HF + UO2F2

When did ya' decide ta' show us your age Jack..

Step 3?

Okay, after I got the gram amounts of the individual elements in the reactants, I subtracted the gram amounts of uranium (2.864 g), oxygen (.412 g), and hydrogen (.051 g) from the gram amounts of the products in order to isolate the gram amounts for fluorine. Subtracting uranium and oxygen from 3.730 g of uranium/oxygen/fluorine compound yielded .454 g fluorine; subtracting hydrogen from .970 g of hydrogen fluoride yielded .919 g fluorine.

Probably when we played the guessing game and figured it out a couple days ago.

I should have been here..
 
I don't get it. How'f you figure oxygen out? It doesn't give us a mass for how much water was added. And how are you getting 0.919/F in the gas? I keep getting 0.921.

The total mass of the products is 4.70 grams. Just subtract 4.237 grams to get the figure for water. You can't gain or lose mass in a chemical reaction, right?

Yeah. Law of Conservation of Mass seems to dictate so.

4.237? Isn't it 4.267?

No, it's definitely 4.237 g UF6.

Water is added to 4.237 grams of UF6 (small 6). The only products are 3.730 grams of a solid containing only uranium, oxygen, and fluorine and 0.970 grams of a gas. The gas is 95.0% fluorine, and the remainder is hydrogen.

How'd you get UO2F2 for the equation?

1. I found the percent composition of the solid product (76.8% U, 11.0% O, and 12.2% F).
2. I converted the percentages to gram amounts and converted them to moles. The mole ratio of the three elements was, like, U.323O.688F.642 or something along the lines of that.
3. I divided the molar quantities by the smallest of the three to yield UO2.13F1.98. I rounded the numbers to the nearest whole number to get UO2F2.
 
Oh...the same thing as number one pretty much...

Well...that's three points earned. Wanna help with the other 12 problems?

Hehehe...
 
At the end of the world,
Or the last thing I see,
You are never coming home, never coming home,
Could I? Should I?

I can't really help you with the other 12 right now. I gotta be going. Maybe during daylight hours...
 
And all the things that you never ever told me,
And all the smiles that are ever gonna haunt me...
 
Wow...they finally gave the American version of FMA a new opening theme...'bout time.
 
Ty.. You're 'singing' Ghost Of You by MCR aren't ya'?

We've had the same opening for over 40 episodes now. Yeah, it is about time.

You are never coming home, never coming home,
Could I? Should I?
And all the wounds that are ever gonna scar me,
And all the ghosts that are never gonna catch me...
