We wonder if someone can help. How to make Rectified Spirit (White spirit) not from grain but from sodium cyclamate. Pls help us Thanks

Boning up on my gas laws here, which law(s) would state that a gaseous compound is composed of a number of different gases, and given the opportunity these component gases will begin to behave independently? Thanks!

the liquid cooking oil, that says vegitable oil or vegitable oil blend is not hydrogenated right? hydrogenated oils are usually solid at room temperature right? i checked the label coudn't find any mention if it was hydrogenated or not. thanks

How does a stable bond causes an element to react and form large number of compounds? Like for instance carbon.

hello everyone i need some help to understand the first law in thermodynamics especially how to understand reversible and irreversible process and expansion and compression in isothermal,adiabatic .....etc

so i have a rather large chunk of chromium, well atleast thats what the seller claims it to be. i have no reason to doubt that it is chromium but i want to be positive or as positive as possible without getting it tested by expensive machines. i weighed it and it on a digital scale that is accurate to 0.1g and it weighed in at 130.8grams based on my measurements with my digital caliper it has a volume of 18.153396 and should weight 130.55291724 (and yes i know the all the extra decimal places are pointless, but im just putting down the exact numbers i got) the rectangle isnt perfect and my tools are not very expensive; so i believe that the density is consistent with …

HCI (s) <=> H+(s) + Cl-(s)

Hello everyone! I'm new here obviously, and I need a ton of help with my science project! My experiment design is due on Monday. I need help because a lot of the information is hard to find on the internet. If you can help me find it too, that'll be great! So my fundamental science project question is: Can tide detergent (or bleach?) remove sharpie from clothes? Why or why not? How? I talked to my chemistry teacher and she wants a lot more information on the chemical analysis/make up of the marker and detergent. She said my experiment is very elementary and doesn't have a lot of chemistry involved to make it more complex. On my first draft, I just put the fact…

does the atomic spectrum emission or absorption by an ionized element change with different isotopes? like would tritium have different atomic spectral lines then hydrogen1 or deuterium? sorry just a random thought that popped into my head

Hi I am new to this so not sure if this is the right place to post just a quick question- I have made the two enantiomers of tris(ethytlenediamine)cobalt(III) tri-iodide. I have then taken the two UV-vis spectra of the two complexes and also the racemic mixture. All 3 absorbed at roughly 460nm but showed different absorbance- the l enantiomer showed highest absorbance and the d enantiomer showed lowest with the racemic mixture falling directly between the two. Can anyone explain why two enantiomers would show a different absorbance - (and therefore a different molar extinction coefficient)? Thanks

so after lots of searching i have been unable to find out if it is possible to do a displacement reaction with thorium nitrate. ive done the displacement reactions with silver nitrate as well as copper sulfate. so i have some thorium nitrate that is my thorium sample for my element collection and i would much rather have thorium metal instead of a compound. is it possible and if it is what metal should i use? copper, iron, aluminium, ect.

I am wondering about the causes of atmospheric pressure. All the sights I have found say that air pressure is caused by the weight of air above a point pressing down upon air below it. This seems to contradict Dalton's law of partial pressure because air cannot press on other air and have an effect. Am I missing something? I was thinking that maybe gravity is more of the reason for the pressure, being that gravity is stronger closer to the core, so the weaker effect of gravity at higher altitudes could cause changes in air density or something. Could somebody help me understand this, please?

A reference I found indicates that at 25 degrees celsius the solubility of NaCl is 0.36 Kg of NaCl per 1 Kg of Water . If there was a mixture of 1 Kg of Water and 0.36 Kg of NaCl at 25 degrees celsius and I stirred into this a small amount of Sugar ( 20 grams ) what would happen to the levels of NaCl and sugar ? Let's assume everything is at 25 degrees celsius , I only provided the numbers for clarity , it is more of the concept that is of interest .

I have always thought about this and ended up getting confused. Lets say you take ice and break it to two pieces, if you want to make it one piece again you can't unless u melt it then freeze it again. I would like to understand why does changing it to liquid enables us to reform the bondings. I want to know what happens between the bondings and atoms ( deep explanation ) Thanks

Lets say we have Hydrogen and Oxygen. When they combine, electrons are shared between the atoms. Do electrons lose energy when this happens?

As wiki states under Thermolysis water heated to around 2500 C will break the bonds of H20 into H2 and O2. If you reached this temperature instantly would the H2O just change into a gas (that would look like thin air) and could the H2 be extracted and cooled out to some storage unit, like a compressor if you were using something like tungsten pipes and tanks? What would happen to H2 at such temperatures? After some more reading I found an Israel team The Weizmann team already started to achieve this back in 1995 (read here). Now they have a brochure claiming a two-step H2O-splitting thermochemical cycle based, in which they have patented it already so hope th…

What do you think about this paper? Can anyone give me some usefull critics wich we can take in to account? Thank you! Link: https://stuiterproxy...s.org+ct100579w , or see attachement! it is without attachement, sorry

Why isn't there one of these in every household? Why haven't I heard anything about this up until now?

Does anyone know what causes Ursodeoxycholic acid to gel in aqueous solution at pH 1.2 and 8.0, but not at pH 4.5.? I make UDCA capsule blend then fill into gelatin capsule shell by hand and no gelling occurs. When we fill blend into capsule shell using automated equipment, we see the gelling effect at pH 1.2 and 8.0. The automated encapsulation is not considered high energy. It doesnt compress the blend so hard that it produces a solid mass; capsule contents are a free flowing powder after encapsulation. I think if we can understand why the gelling occurs, then we can prevent it from happening. Does anyone know how the crystal structure might change during encapsulation,…

in your opinion, who is the best chemist alive.. right now

So today I learned about sigma and pi bonds in my chemistry lecture today. As I'm doing some of the exercises, I'm stuck in the bonding of allene ([ce]C3H4[/ce]). Is it possible to have orbitals share pi bonds? If I'm doing this correctly, there should still be p orbitals on all carbons after the sp2 orbitals that don't mix with any other orbitals.

From any wavefunction we can determine the probability of where an electron may be. I don't understand the rationale of taking the square of R( r ) instead of using its absolute value. Could someone explain this? NOTE: I haven't taken surface area into account yet.

I need to find 2 chemicals that are safe for school use and that react safely that would be able to reach 100-200c thanks

Hello, Something I've regained an interest in as of late is the extraction of aluminium from pop cans. Typically this has been a desirable thing for the avid soda can collector. However, generally, such an individual brings the pop cans to a recycling center. What I'm curious about is whether or not various chemical methods have been undertaken in order to separate the aluminum from the soda cans. A kitchen chemistry kind of way that is not too expensive, perhaps catalytic, and the materials used can be retrieved with decent yield with a lost cost. Furthermore, there would be the need for the aluminum to separate out (perhaps precipitate to the bototm), for eas…

I have been told that you can pump water over the surface of magnesium and create heavy water. I am hoping someone can help me understand this process. I need to create 10 lb. to 14 lb. per gallon water using well water in open ponds, catch basins, or tanks. I need the process to be low cost. We are also needing thousands of Gallons. Thanks for any help!!!!!
