Alright everyone, it's been a long time since I've been on here but I've come to realize it's really helpful so I've started visiting again! Anyways, I have a little confusion about the inflationary framework of the universe. So... I've been reading this book called The Fabric of the Cosmos by...

How could it be an acid without hydrogen atoms?

What determines a substance's viscosity? Is it a molecular pattern or something of the sort?

Yeah, OK, but can viruses produce poisons?

I need to clear this up: the difference between poisonous and infectous. Apparently infectious agents are living organisms like viruses and bacteria, while poisonous substances are, well, poisonous. But can't viruses be poisonous?

So it is parralell to the water. I get it. I'll see when I have time. I need to get everything first, and the new MP3 player I bought has left me with 30 bucks.

Yeah, I know, but I thought the electrolysis sounded kinda cool. How does the Anode do anything if its not touching the water?

You bet! Already working on getting NaOH.

I'm trying to get the hydroxide. How do I keep the chlorine from reacting with the NaOH? When I was researching I saw that you can put a Nafion membrane to keep the two products seperated.

How dangerous really is the chloralkali process? I know chlorine is formed, but can I bubble it into a tube or something?

Thanks, I think I'll do exactly that. Now, where to start?

Pure water is neutral. However, minerals and such in natural spring water can make it either acidic or basic.

I'm going to get back to experimenting soon and I would like some experiments. Something cool, fun, but with a meaning, a goal. Useful products would be fun, too.

Well, confining within the laws of science, it cannot be perfect. But, you can try to find the greatest voltage possible out of a stable battery. As chroot said, lithium-ion batteries are the best, but you may be able to go higher than that.

How did they get it to turn so green? What's your name, rctrackstar?

I am learning, on my own, with the help of textbooks kindly given to me at Christmas by my grandfather and my own experimenting, some more advanced chemistry than what I studied in Grade Seven. Partly as preparation for High School, and partly for my own knowledge. However, I ran across some...

Actually, I believe that one in every 70 000 000 molecules of hydorgen is tritium.

Insult To Injusry is good.

What about the French League? I know Lyon ogt out by Milan but still, they're an insane team. But if I were to go with the options up there, is La Liga the Spanish Premiera Division or the German Bundesliga?

What do you mean? I meant the Internal Combustion Engine.

What will replace the gasoline ICE? Personally I go with Hydorgen Fuel Cells, but each his own opinion...

True dat. Do some REAL experiments. Real fun, real cool.

Well, I was using a textbook. My level of chemistry (Grade Eight) is not very advanced. Thanks for averything.

Well I ended up doing dome theoretical experiments. With NaCO3 I tried to find some answers: NaCO3 + H2SO4 --> NaHSO4 + HCO3- (What happens to the HCO3 anion?) NaCO3 + HCl --> NaOH + Cl + CO2 (I am not at all sure about this one. I had to re-do it a couple of times and I still don't know.)...

Thanks guys. I wasn't really thinking of electrolysis when I first asked. However, this is what I ended up doing in my research: I tried to figure out some reactions. With NaCO3 I tried to find some answers: NaCO3 + H2SO4 --> NaHSO4 + HCO3- (What happens to the HCO3 anion?) NaCO3 + HCl -->...

Can I get Na or NaO relatively easily and using not very complex/unfindable chemicals?

When you calculate the two moments for the law of the levers, they are supposed to be the same, right?

About the discussion thing, it sounds cool. Should be fun. Good topic, too.

Wow, how come so little?

Well it's for use in a fuel cell. I want to trap the waste heat in a special chamber. Inside that chamber there would be a heat absorber. There's a chart on a website that said that helium had the highest heat capacity, hydrogen excepted. But what you say is also true, if I could get...

Thanks I've just found out a whole lot out. So for my fuel cell, it looks like I might want to use helium as my heat absorber. It'll lighten up the car as well! :smile: :biggrin:

Are there materials that can absorb/trap heat and accumulate it efficiently?

Did my answers help? I'm just trying to be helpful, but I think these guys know a lot more than me.

Up here in Canada we have so much fresh water that we haven't even heard the phrase "desalanation plant". I don't even know how they work.

It's really about what the atoms do or how they bond, but also the specific molecule or atom can be harmful to our health. If you have a harmless molecule, you can transform it into a harmful one by changing the molecular structure. Olive oil, for example, can become carcinegenic if cooked. So...

What we consider poisonous is something that if taken will seriously affect our health and possibly kill us. The chemical, however, is any chemical that is harmful to us. Let's say. we can consider HCl poisinous because it would probably kill us if we decided to drink it. For combusting, it...

People just don't realize that there is a homework forum so they assume that the chemistry forum is for chemistry homework questions. I think people should scan the website better before choosing where to post.

Well the fruit would be rather flammable. I don't know if it will ripen, theough. Why don't you try it?

Thanks I'll do that.

I got to learn this stuff for my fuel cell project. Anyone know any good websites on it?

I am using a 50KW unit that would likely be used in cars as a model. The turbine won't be very big, but just enough to produce some extra electricity. Tests are still to come.

OK, well basically it traps the waste heat from the fuel cell and keeps it hot. Then that heat makes the Stirling engine work. The heat is conducted from the fuel cell out through a vent where it is taken by the thermal room. There can also be storage of water vapour inside the thermal room.

Here are the descriptions of two of my designs. ET1: Turbine and Electrolysis System The Turbine: I have used the water vapour exhaust of a PEM fuel cell to run a turbine to make electricity. After the water vapour has passed through the turbine it goes to electrolysis system. The...

Thanks. How much for a year? $25 U.S.?

What are some practical ways? Because the website says to lower the voltage input, but if I have a catalyst, won't the catalyst just use all that extra voltage anyways? I heard sodium hydroxide is a good catalyst for the electrolysis of water.

If I use a catalyst, would I will be lowering the overpotential?

I couldn't find where I could upload an avatar in my profile.

And could I therefore save electricity? Where before the activation rate was higher and needed x amount of electricity, now to make the same amount of hydrogen I would only need y amount of electricity, where y<x.

Could I speed up the reaction of electrlysis by using a catalyst?

Thanks a lot for all the help.
