I was thinking about a possible scenario and a possible answer to a problem. Yes, I know this seems quite disturbing, but I'm being serious. Imagine that you're in the desert. You haven't been able to find water, but you've found animals around. These animals are dying, yet you could kill them for food. However, you're running low on water. A thought crosses your mind, "Could I drain the blood into a pot and boil it for the water?" What do you think? Could such a thing be possible?

can someone please. explain what the reaction is. thanks. an is it powerful enough to explode a human stomach. my friend an i had a debate. an i dont belive you could eat a packet of mentos, chew them up.. get them in your stomach.. then straight away drink like 2 litres of diet coke. an then you stomach will explode. is that at all possible? what are the circumstances where your stomach would explode. like what would you have to do? drive the coke 1st an then eat the mentos? or what.. thanks...

I bought some citric acid yesterday, and have yet to find a use for it. Other than culinary applications, what can I do with it?

Hello, I have been looking around for plastic pigments or colorants . I want a black colour and I am using ABS plastics. I have seen some pigments but they are mainly red and yellow colours ! Does anyone have any idea if there is such a thing that would be suitable ? Thanks !

This is a real classical experiment, but it is always fun to do it. http://woelen.scheikunde.net/science/chem/exps/nitrocotton/index.html This makes nitrated cellulose wadding, which IIRC also is called guncotton. It burns really fast with a brilliant orange flame. Have fun, but please be careful!

Hi, can anyone tell me how much toxic a phenol solution is. For eg. is a solution of 100 mg/L dangerous, if prepared in lab without hood?? Till what limit can we prepare a phenol solution without vent hood??

Does anyone know the difference between molecular absorption spectroscopy and atomic absorption spectroscopy? I know AAS destroys the sample, but I need to know another diffference? I tried searching but can't really find anything about MAS. Is there another name for MAS? Thanks, fo

In iodometric titration, why do we add the starch solution when it is close to the end point instead of pouring it at first?

In chemistry I recently did a lab showing how temperature relates to the pressure of a gas. We used what I believe was called a Gay-Lussac device. It was placed in water which was heated and then the pressure of the gas inside the device was measured. We estimated absolute zero with the data we got and our estimate was -276. My question is if the gas temperature inside the device wasn't the same as the water temperature how would this affect the measure of absolute value and if the sphere in which the gas was contained expanded how would this affect the estimate of absolute zero. Hopefully I explained that well enough.......I really appreciate your replies. than…

I got a chemistry model building set (balls and sticks), and it came with carbon atoms that have 4 holes (which makes sense) but also with carbons that have 5 holes. I never knew that you can have carbon molecules that can make 5 bonds. When does it do this?

How do I find out initial amounts of a equilibrium problem if one or some of them are not given ? Ex: Equilibrium is established in a 2.50-L flask at 250 degree celcius for the reaction: PCl5(g) -> PCl3(g) + Cl2(g) Kc= 3.8x10^-2 How many moles of each molecule is present, if 0.550mol of each PCl5 and PCl3 was initially introduced into the flask? .. thanks

Does the molar volume of a given quantity of gas depend on the type of gas?

A colleague of mine ignited propanoic acid. The resulting smell was described as quite unsettling for him and some of his students. He then attempted to ignite glacial acetic acid which does have a flammable symbol on the reagent bottle. However, he could not ignite it. Can anyone enlighten(no pun here) us high school chemistry teachers why we weren't able to ignite flammable glacial acetic acid? Thanks Ferdinand

Hey, Today I saw on a TV program these people prove that using coke and some tin foil to polish up chrome. It did a really nice job ! better than they leading brands at the moment !Does anyone know what it does that makes coke to effective at this :S ? I can't see anything it could be !:S

Does anyone know a great site with many AP Chem Labs? I'm looking for AP Labs on these Topics: Fireworks-Related Labs (How is Fireworks related to Chemistry, Btw) Electrolytes in Sports Drinks vs. Water (something with electrolytes) Cleaning Reagents-related Chemistry of Foods Thanks

Hey I have been looking about at silicone oils to use with boric acid to make silly putty. I have found a place that can supply silicone oil but i could do with some advice on the viscosity of the silicone oil that I should use for making silly putty. Low Medium High etc.. Would mixing boric acid with white glue work as well ? I want to buy some of this stuff and find out but i want to make sure im using the rite thing Cheers !

This might seem like a pointless thread, but I like to seek the wise council and hope they could give some insight, input, and/or advice. For those of you who aren't American, there is a test in America that allows people to earn college credit for passing a test. It's a nice way of flying out of courses if a person has previous experience. However, if a person screws up the first time, then he or she can only take the test again after 6 months has passed from the previous testing date. So, if any of you are in America and think you've got some decent experience, you might be interested in taking it. (Each test costs about $60 USD. An affordable way to get college…

This morning I was heating up a large pan of oil and I noticed that when the oil got to a certain heat, small bubbles of gas would form on the bottom of the pan and rise to the top as water does when it boils. This confused me a little as I always assumed gases cannot dissolve in non polar solvents. Does anyone know what was going on?

Does anyone know how to make a small but strong EMP generator?

Hello, I have some salt dough that i made and i am wondering if there is any way of preserving it permanently. If it was sealed away from any air would it be preserved until exposed to air ? Or is there anything else with the same sort of consistency of salt dough that does last forever ? What gel do they use in Gel mouse pads ? Any ideas ? Thanks !

Yo, Can someone anwser this questions from me? 1. Witch electrode work better in a NaOH Solution Lead Oxide on Clay or just a plain lead strip? 2. How would you sterilize biologically a Petri dish with out expensive equipment? 3. How do you grow penicillin from orange mold? 4. When you are grow biological spesmen should you put in the light or dark and should you in a cold, warm, or hot place 5. What are the acids, alcohols, and steps to make esters? 6. How do you make Zinc Sulfide out of Zinc and Sulfur?

Will 30% Hydrogen Peroxide light in fire with a match?

Form people who bought a Burette from Home Science Tools, How do you adjust the clamp, because in the picture it looks like you'd take off the clamp and it drips or streams out and you put in on and it stops?

Why OXYGEN supports combustion ??? What is the chemical reactions OR mechanism take place >>>????

Hey, I'm wondering if it is possible to safely mould plastics. I know the problems are that it gives of toxic fumes and often chards before it melts. But companies do it using some sort of powder ? Then they simply melt it and mould it and allow it to chill. Does anyone know what the plastic it is that I can use ? It needs to be strong when it solidifies . Also I need a material I can mould it in which can easily be shaped etc ? Can anyone help me ? Thanks a lot !
