HazJr needs a hand understanding stoichiometry and I am CLUELESS!
-
My chemistry goes as far as making
moonshine, homemade wine.... ::)
sorry,.....
best I could do,...

Sounds like something you need see the doctor for.
-
TW,
He can do the math he just doesn't understand it. Need someone that can explain it to him.

Yes, and then he can explain it to us.
I see where the numbers are coming from, but when you have figured them out what question have you answered ?
-
It's a conversion of some sort. He tried to tell me but I never even took chemistry that alone advanced chem.
-
It's one of those things that I ignore because when you don't know enough to understand the questions, answers aren't going to do you any good ;D

It's been thirty some years for me too Haz....
this one from TW's post seems promising..

Hey! Ya hit 10,000!
Damn, you got diarrhea of the mouth! ;D

Yes, Peg was asking if I was going to hit it tonight, guess so ;D Comes from being opinionated and unemployed ;D
You people get to read all the stuff I USED to mull over while I was running a machine ::)
Based on the link Tim quoted, it seems to be reducing to the common chemical denominator.
-
Sorry Haz. It's been way to long since I had any of this and that was just a basic chemistry class in college. The last time I looked at some of that stuff was when my kids were in middle school. I got out some of my old college notes and they were studying the stuff I had in college in middle school.
Some times you just have to walk away from it for awhile and come back to it later with a head that is not cluttered in frustration.
Not suggesting that Haz Jr is a dummy, but I am, and have found that the "For Dummies" books are a great help to me in a lot of things to get the background to understanding the tougher things. They probably have one for Chemistry
-
The "for Dummies" series is actually one of the best selling reference series in the country, with a well earned reputation of reduceing complex things into a form the ordinary non "geek" can comprehend.

I've got a bachelor's in Biochem. Worked in a research lab for a while doing analytical chem, which deals heavily in stoichiometry. If you post the question I'll work it and try to post an answer and explanation of the solution. The big thing with stoichiometry is you have to make sure you have your units correct. For example a question gives you information you need in say Kg, but you have to convert to grams to use a certain formula.

Doc, First, THANKS!
His question seems to be 'why'. As in what good is it when he doesn't see the need for it.
Could you call me tonight? I will pm you my cell number so you and he can talk.

Welcome DocWannaBe, this forum continues to have a vast resource of members, and even in stoichiometry. :o Hope you can help HazJr.
Might need you to provide the recipe for smokeless powder if ammo gets any tighter... ::)
-
I'd have no problem giving you a call, but I'm new here. Where do you click to see your PMs?

Look at the top of the 'forums' page. It will say you have a new message. Just click on it.

This forum continues to impress me everyday! Now we got us a chem type! Doc was nice enough to call and is on the phone with HazJr as I type.
Is this a cool place or what!
THANK YOU, DOC!
(who needs Google...I have DRTV!)
-
That's GREAT, this place is a genuine resource center ;D
-
Welcome Doc,
Stroll on over to the new member intro and introduce yourself. Thanks for helping Haz and his son.
-
I can help.
Chem was my OG minor in College. til I changed it to Structural engineering.
Math is another one I can help with.
-
Haz,
Glad someone could help on the question. All I remember from high school chemistry is that I thought it would be a good idea to put Francium into the school fountain, but the teacher didn't think that was such a hot idea. ::)
I was a little pyromaniac back then......... ;)
My undergrad and grad stuff was in finance so I can help with economics and finance stuff, plus some computer science/info systems questions too.....

Our chemistry teacher actually put a rather large chunk of pure metallic sodium into about a liter of water during class one time. We all managed to get out of the room - at his rather loud and insistent instruction BTW - before it blew. It was an accident, but then he seemed to have a number of those "accidents". Nothing intentional, just a bit on the distracted side. Nice guy tho, family friend too.
A pyro huh? Did you almost burn your house down? I did. Also built missiles out of savaged M1 cartridges and some powder using curtain rod tubes as the launchers. Played with fires in the city dump, using cast iron waste pipe as mortar tubes, dropped aerosol cans nozzle end into the tubes with one end in the fire.
That's all I'm going to admit to.
-
S..T Haz,
I got a headache trying to read and figure out what it is! Back in the dark ages when I took Chemistry I don't even think Stoichiometry even existed.
Richard
PS: Glad you found someone to help Haz Jr.
-
High School Chem but since forgotten most of that.....
Mostly due to C2H5OH, aka ethanol, the primary ingredient in your Hazarita's..... ;D
I hope the Doc was able to help the young-un!

I always thaought that was a "right of passage" groing up. Today it falls under terrorist regulations.
Yeah, I almost burnt the house down. Potassium permanganate and glycerin. The spontanious combustion didn't work so I threw it away in the waste basket. Then it worked. There was also the super smoke bomb mixture that went off in the house during the "cooking" stage on the stove. I had to get creative to get some of the ingrediants so I created a "laboratory" to have orders shipped to as many places wouldn't sell to individuals. I probably had enough stuff stashed away in my bedroom closet to level the whole block. I wasn't out to create mayhem on society, just liked to make things go bang. I'm sure the lefty liberal would wet their twisted panties at some of the stuff I played with. The statute of limitations has expired.
Then there was the model rockets with a little extra bang added.

None of you should feel bad about any little "oops's" you may have had, Francis Bacon blew himself up several times. ;D

And Bacon's dead, what's your point? ;D ;D
-
Haz if you've got a college or even a community college and about $15 an hour or so, you can probably round up a tutor. They will probably want a copy of his text and notes as well.
FQ13

It was old age that killed him, not "explosives for fun and fame" ;D

Hazcat,
I quit balancing equations years ago. It could be those brain cells died around 1985.
I'm glad HazcatJr is good at math. He'll need it for Thermodynamics.
I tried to help a friends daughter with that and realized I never understood it.
-
I want to thank all who tried to help and especially Doc and Tab, both of whom I and or my son talked to via phone.
Once again DRTV proves to be an invaluable source and a true family.
-
you know haz you got me in trouble with the wife... she was trying to call me all that time.
Sucks she is coming back home friday morning and I leave friday night for a week. :'(

Hey Haz, if you haven't found a workable answer yet, go to : http://en.wikipedia.org/wiki/Stoichiometry and I think you will find what you are looking for. If I recall my own chem classes (and chemestry was entirely too good to me to enable much recall) it has to do with atomic weight (how much an atom of stuff weighs) and valences (the electrons in one element that combine with the electrons in another element to make a compound). Reactive stoichiometry is just the math involved in determining how much of what you will have when you start with known amounts of elemental stuff--and how much reaction or release of energy will occur when the combination happens. It's all sort of useful to know if you are creating things that go boom.
