I suppose a "water trough" keeps the water off the bench!

Glass tubing has practically infinate uses in a chemisty lab - generally it is used because it is inert to mose chemicals. It's also...

things you'll need to solve the problem:
1) #molecules in a mol (Avagdro's number)
2) molecular weight of CO2 (units are g/mol)
3) #moles CO2 in 200 mg (200mg = 0.200 g)
4) #molecules CO2 in the...

Is there any particular piece of equipment or glassware you're interested in?

Hello all. I’ve got a Price Pfister single-control kitchen faucet, about 1.5 yrs, with a low flow problem (both hot and cold). I took the aerator out about month ago, with no improvement; it seems...

Hi all. Does anyone know of an easy way to get old plumbers putty off/out of pipe threads? I need to remove the locknut on a bathroom sink drainpipe, and the threads on the pipe are full of old,...

Hello all. I need some advice on a few things I discovered while cleaning out the gutters last weekend. The house is in North Carolina, built in 1994. I’ve had it only a few years and I don’t...

I have Acrobat Standard v7 at work and need to integrate multiple print jobs into a single PDF. I know this is as simple task with Acrobat, but it's tedious if you have to create a lot of these...

Try posting the question in the plumbing forum (home > home & garden > plumbing). There's a veteran user/plumbing expert there (speedball1) who is usually very quick to answer new posts.

Hi all. My HOA has asked me to paint, or replace my front door. There's really nothing wrong with the door, or jambs, so I'm not interested in buying a new one. The door is steel, with a faux...

I think this problem is supposed to make you do some detective work. I thought this was a neat puzzle, so I typed in my 2 cents. I'd say intro organic chemistry, but it seems a little more...

The position para to the OH group in 2-napthol is "blocked" by the junction with the second benzene ring. If you had 1-napthol, it would react at the para position. In a lot of cases, the...

Thanks, guys. I took a close look at the top of the door, and it doesn't have J channel. It looks like some sort of aluminum flashing. Anyway, I'm going to "peel" back the siding again to try and...

Hi all - let me preface my problem below by saying I’m a fairly new homeowner, and don’t really know much about vinyl siding. I suspect I’ve done something wrong, but I’m not really sure where I...

Does anyone know where I can find a repair manual for 98 Subaru Forester? I can find only 2000 - present manuals (... any real changes between 1998 and 2000?).

Thanks!

Several months ago I had a handyman replace a pre-hung entry door leading out to our deck. Last night I noticed a small water stain on the subfloor under one of the pieces of interior casing. I had...

The blue primer is in the seam between the 3" ID vertical pipe coming and an elbow that goes under the slab (this seam is about 2-1/2" below floor level). The bottom edge of the flange doesn't have...

Without think about it too hard, balance the equation:

CoCl2 + Na2CO3 ----> CoCO3 + 2NaCl

Which product do you suppose will precipitate?

Hey speedball1 (and anyone else interested)... after some thought, I decided to pull the toilet up again before committing to caulking it down. At very least I thought I should jam lots of plastic...

I recently pulled up the stump/roots of a shrub that was about 2 feet from my house, and think it might have been, or was being eaten by termites. We cut the shrub down last year, so the stump was...

Do you want to know what is good structure-drawing software, or how to interpret the name?

Thanks, Tom. I think the flange is an "inside" type already - is there an easy way to tell for sure? If it is, can it be easily cut out and replaced, or would that be a really big job? Right now...

I discovered the toilet flange in our downstairs bath is about 3/16-1/4” above the concrete slab. Maybe this clearance was left for subfloor/tile that never got installed. Anyway, the toilet rests...
