What is the effect of adding NaOH and Al with H2O? Is the reaction--2NaOH + 2Al + 2H2O → 3H2 + 2NaAlO2??

I belive this to be the reaction involved in using Drano and I was wondering if it would be effected by the temperature of the H2O and if the reaction would be effected by NaCl mixed in the H2O.

Engine Cumbustion & Etc.

I've been knocking around an idea in my head and I was wondering if anyone had an answer to a few problems associated with said idea. One of the problems/road-blocks is how do modern cars run? More specifically, is the gasoline that goes into the pistons for combustion an actual air/gas mixture, or is it air/liquid-gasoline? And is there a way to manually adjust the ratio of air-to-combustible? The reason I ask is because I was hypothesizing whether or not it would be feasible to replace gasoline with a more efficient combustible, and this combustible would greatly depend on what is actually put into a modern petroleum-based car engine's pistons. Thanks for any info!

Poseidon- High Powered Modified H2O Rocket

Just thought I would give those interested a sneak peak at the Poseidon's main booster module.Construction-12 x 1.25L Soda bottles spliced with external sleeves using Sikaflex 11FC.The Poseidon's booster module is not yet complete, it has another 7L of capacity to be added. The booster will then be combined with several other modules before Poseidon is ready for launch.You may also like to note the quick attach/release fin system. They are saw toothed sign holders normally found in stationary shops. They allow the fins not only to be attached perpendicular to the body, but also provide a reproducible fixing method.Although this is not my preferred method of splicing, Aircommand.com has put together an excellent tutorial which can show you the principal. My method (which I DID NOT create) involves shrinking the inner bottle with our curled lip. Air command in that tutorial reduces the outside sheath from a larger capacity bottle to suit. The method I use does not call for the use of different sized bottles or a blow torch, just boiling water. Air Commands Splicing tutorialAircommand.com

Extract heavy water?

I can't get hold of any heavy water so I want to try extract it from normal water, I only need a drop or two. I was gonna use electrolysis to separate the atoms and increase the concentration if heavy water till it gets to around 70% (min.) but how much of power do I need to pass though the wires to only separate H2O and leave the D2O? (Need the deuterium for a fusor I'm building)

Does synthesizing Sodium Chlorate NaCl03 produce any harmful fumes if i electrolyize the solution while it is hot?

Does synthesizing Sodium Chlorate NaCl03 produce any harmful fumes if i electrolyize the solution while it is hot? I saw on wiki if you heat the solution while electroyzing the solution the reaction is NaCl + 3H2O = NaClO3 + 3H2 but if it isnt hot the reaction is 2NaCl + H2O = NaClO + NaCl + H2O , NaClO (Sodium hypochlorite) is what is used in household bleach. DOES THE SAFE VERSION PRODUCE CHLORINE FUMES?

What's the best design for a water rocket?

There's two parts I'm wondering about: - fin design - recovery system design I'm planning to use angled fins. What angle is best? Does the shape of the fins matter, or can I just make triangles out of cardboard? For the recovery system, which is better: airspeed flap or "nose separates at apogee"? The second one is definitely easier to build, though.

AirDrop Irragation

Anyone  ever heard of this airdrop irrigation. http://www.jamesdysonaward.org/Projects/Project.aspx?ID=1722 Sounds pretty amazing, in the vid he talks about producing 1 liter h2o a day with a small one he build at home. I'm thinking the fan could be replaced with a sun pipe.

Two chemistry related questions.?

I have three chemistry questions. 1) What is my result when I mix baking powder(NOT sodium bicarbonate)and vinegar? 2) What is the result when one burns steel wool? Is Iron Oxide my end result? 3) When mixing vinegar and baking soda if I were to keep the mixture under pressure would the water and co2 stay as carbonic acid or still decompose into h2o and co2?

I have used bleach to make rust(with salt), how can I seperate the rust from the salt? Answered

I was looking for a way to make rust (ironoxide) and found that bleach coul be used as an oxidizer; however, I would not know when it was finished breaking down. With some research I found that NaClO + H2O2 -> O2 + NaCl + H2O. I think I can use this to either: use the NaClO and make the ironoxide, then add the H202 to break do the residual NaClO (extra H2O2 can be evaporated with the H2O), or used the reaction to speed up the ironoxide making with a bit of extra H2O2 to insure all the NaClO is used and the evaporate off the rest. (which would be better? would be my first question, but not the most pressing one) My question is how can I sepperate the Iron oxide from the NaCl (salt), since both are water soluble (sp)? A filter will seperate out larger pieces of ironoxide, but there will still be a fair amount that passes through the filter with the salt and I would like to minimize my loses as much as possible.

H202 production

Wondering if any one have come across a video showing the steps or know how to do this and how to extract H2O2 form the solution to make hydrogen peroxide like discribed from wikipedia article http://en.wikipedia.org/wiki/Hydrogen_peroxide#Manufacture i know i just cut and pasted to make it easer the history  barium peroxide with nitric acid. An improved version of this process used hydrochloric acid, followed by sulfuric acid to precipitate the barium sulfate byproduct.  Sodium peroxide also makes H2O2 Na2O2 + 2 H2O → 2 NaOH + H2O2 those are hard to come by for DIY and thought maybe this would easier  inorganic processes were used, employing the electrolysis of an aqueous solution of sulfuric acid or acidic ammonium bisulfate (NH4HSO4), followed by hydrolysis of the peroxodisulfate ((SO4)2)2− that is formed. peroxodisulfate commonly referred to as the persulfate ion

Strange Planet

Life is very weird. But it makes sense, consider the the physics and the atomic properties of the materials constitute existence. There are few materials as counter intuitive as good old H2O. Water is so strange, yet is a chemical we deal with everyday. It's what makes life possible, but as Neatorama explains, water is a very Funky Fluid.Oh, hey, I'm sure many of you have heard about the dangers of Dihydrogen Monoxide too. Just take this as my warning in case you haven't.-Neatorama -Photo by: Liquid Sculpture, check them out for some beautiful drop photography.

Can you use nitric acid + sodium hydroxide to make sodium nitrate? Answered

I am trying to make some small rockets and I can't get or make KNO3 (It's banned and I can't find potassium chloride in any supermarkets, if you know where to find it please tell) so I have been making sodium nitrate out of ammonium nitrate and sodium hydroxide as a substitute, so in trying to make the process cheaper I have found this HN03 + NaOH = NaNO3 + H2O will this work?

Our main source of  energy right now is nuclear energy. Although Nuclear energy  might seem to be a reliable source of energy, it is not.  Nuclear energy is not a reliable source of energy  because you need to extract Uranium ore from the earth's core which might seem as a good  source of Uranium it is not. This is not a endless supply  of uranium because it will eventually  run out of uranium .   So what can we do to solve this issue? The answer is alternative energy.  Alternative energy  is energy that can be renewed  and that is reliable. One solution is replacing Uranium fuel rods in a reactors core with Tritium. Tritium can be used  as a substitute for uranium because it has the same properties as uranium except that it has a shorter  half life.  Tritium is made by fusing solid  Hydrogen With Lithium  in a Farnsworth reactor.  This also has its problems one major  problem is the radiation and heat that is generated during the process  of fusion. Tritium can be then used as a fuel  pellet for a Nuclear reactor when it is mixed with Deuterium which is a solid. Tritium is also a good fuel pellet because it only has a life span of about 12.4 years, then  it decays into Helium 6 which is very harmless. Uranium on the other hand is not  safe because it has a life span of about 2000 years and it gradually decays into other radioactive material such as Thorium, neptunium, ECT.... This is Called the Uranium - Thorium cycle. The tritium is also ecologically friendly because it  can be made from H1 which is found in water H2O.  H1 is called Portion and is extracted through a process called electrolyses in which water is charged by a D.C current.

Tracing Plastic Water Pipe Underground.

Earlier today, while removing tree stumps, on of my crew struck water. The theme song for the Beverly Hillbillies came up. "when up from the ground came a bubbling crude! ...oil, that is... " except it was water, and we went scrambling to find the water shutoff. Lawn Sprinkler systems usually have plastic pipe a few inches underground.  No metal.   :.   Can't find it with metal detector. Potential Options: AC wires can be tracked through walls by the electromagnetic flux around them. Stud sensors today also have a circuit for AC wiring. Could something like that be used?  Although city water has some minerals in it, does it have enough to conduct electricity well enough for an electric pulse sensor? If the water in the system was temporarily made salty enough for an EM signal to be traced, would it mess up the lawn once you dumped that salty h2o? Whata bout conductivity of a fertilizer mix? Medical scans- barium- mildly radioactive. mmmm.... yeah. right. Chemical sniffers- sniff out those semi-soft pipes? Like dogs sniffing out contraband in the airport... Use water flow to carry a fine wire through the pipe, then track an EM signal in that wire. sonic imaging (or at least detection- like the stud sensor) ground penetrating radar... That's all I can think of.  Every option I can think of has issues. Is there any precedent for something that works in this situation?
