I read in my text book that alcohols like methanol don't react with strong acids like sodium hyroxide. They will react, however, with organic acids. Why is this? Does this apply to all weak acids and strong bases?

What are the balanced redox equations that take place between Ammonium Molybdate [(NH4)6Mo7O24:4H20], Stannous Chloride [snCl2:2H20], and Phosphate that form Molybdenum Blue [Mo5O14]?

Hi, I'm new to this forum and am trying to produce Fe203(RUST aka Ferric oxide) through electrolysis. I have attatched a thick copper wire to the negative(black)lead and a normal galvanized steel nail.(I think its galvanized, its the kind that is not all rough, it is smooth and kind of gold/bronze). Anyways I want to make sure im not making Acid rust, the opposite of rust. When i do this i yield a thick goopy black/grey liquid that contains only the tiniest trace of rust in it. From what i have heard this is supposed to make rust on the nail and I should scrape it off and let it accumulate. The metal is disentegrating also. The copper wire bubbles and withing 5 minute…

Dark-colored clothes absorb light thus retaining more heat as opposed to light-colored clothes which reflects light. So let me ask, what if person A is wearing a grey sweater and a white undershirt. And person B is wearing a grey sweater and a black undershirt. Would B be more warm than A even though the undershirt is covered by the sweater and is not hit directly by the sunlight?

I am an 11th grade student who just finished the AP Chem test. My teacher has everyone pick out a lab to do for a final grade. I was wondering if anyone knew of(or where to look for) a challenging lab that was interesting(maybe covers a topic that isnt usually covered in an AP Chem class) that is doable in about an hour and a half, and can be done in an average High School Chem room.

when Na+ combines with Cl-, we get NaCl. Which orbit does the electrone take? Na or Cl?

Hi. The instructions were to have 2 test tube filled with 10 mL of water in each. Then dissolve 3g of NaNO2 (sodium nitrite) in each test tube. Only take 1 of the test tube and put it in an ice bath so it reaches 0 degrees C. Insert 5 mL of Glacial Acetic Acid into the cold solution. You just leave the other test tube alone. After these procedures i noticed that the top half of the cold solution was bubbling and had a light bluish color. The bottom of the tube stayed clearish. The point of the lab is to figure out why the colors of the 2 test tubes varied. My opinion is that the NaNO2 and HC2H3O2 had a double replacement reaction making HNO2 and NaC2H3O2. My t…

Hi, My sister is going to graduate in a few weeks and a couple of my friends an I plan on throwing them a graduation party. Part of this party is pyrotechnics (of course ). Now one of her friends requested an exploision. There are many different ways of making things explode.. but I figured if I'm gonna blow something up, why not make it spectacular. What I want is the type of explosion that is very 'firey'. Not just a dry 'bang'.. now the main problem is this: I do not want to use any volatile substances.. no gasoline or pretty much any hydrocarbon. I want it to be as safe for them as possible.. of course its never really safe when dealing with these kinds of thing…

I just want to ask why heat is released in a reaction between magnesium and hcl.

I ignited a planty material in a porcelain dish at 900ºC, to see its ash content, but i saw some rection took place between the dish and material(which is of vegetable origin). Can anyone help me in knowing what could be the material that has reacted and how to remove that material from the dish, so as to analyse it further, and also how to clean my porcelain dish.

Two or Three year ago there was a ever bad fires that got close to Los Angeles, I was wondering what is the chemical composition of ash? And what does it do to your lungs and body in detail? -Or is it just carbon

I myself (thank god) never had an accident with acids. So I started wondering how bad an acid burn 'burns'... Well, to satisfy my curiosity i dunked my finger in 6M Sulfuric acid. Not the smartest thing to do I know, but I was curious. To my surprise I felt nothing. Now I know if I left it on my finger for a while that won't be a good idea. So I wiped it off on my lab coat. Well, right now and hour later my finger is fine and I'm typing this post. My question is just HOW concentrated does an acid have to be for it to start burning almost immediately. (Now I know if I try this with 18M Sulfuric acid I will probably end up losing a finger or somehthing but I'm just wonder…

is it possible to be "invisibally smacked" from an explosion?IE- MI3 Cruise gets slammed into a car, falls down, and gets back up running. To me, its impossible. Im sure an explosion makes impact with air causing a "jolt" but i would imagine that jolt would be apart of the combustion, meaning intense heat would follow such a jolt. So am i correct that Tom Cruise would have been charred when he was slammed into the car? I just want to clarify, thanks!

Hello, I am looking for a product most likely a gel, which can be used in some sort of rubber coating for comfort. You all have probably seen the bike saddles that are filled with gel. Well I am looking for something like this really. Something that would be better for the hand though. So it would mould into the hand for comfort. It would be good if it would also reset in the original position. I originally thought of using Corn Flour which is good!. Could anyone please help? Thanks a lot

For Chemistry we need to design and perform a practicle to determine the enthalpy of combustion of oly foods. We hve been told that the oily food we will be using is a variety of nuts. We have only just begun learning about enthalpy in Chemistry, and so I am not sure how I to design a method in order to determine the entahlpy of combustion of a nut. Would anybody be able to offer any assistance?

could anyone pls tell me which solvent to use for uv spectroscopy of powdered wastes from the paper indusrty? ive already tried 1,4 dioxan, phenol, distilled water with no success... can dichloromethane be used for uv spectro?

Hi im very very new to these forums - I joined because it looks like a pretty cool place - and interesting lol Anyway I studying science and have about 23 hours to hand in all my coursework - im stuck on a question and if anyone can help that would be sooooo cool - cheers.. We are studying the production of copper - we produced a pure sample of it using malachite and carbon, now I have a question but dont understand it ---- Give a balanced equations in the production of copper from malachite copper (II) carbonate ---- thats the quesition but has lost me completely. If anyone can help that could be great - thanks xxx

When I was a spotty teenager 20 years ago I was impressed by the experiment at school where a piece of Sodium metal was placed on water, and it caught fire with the released hydrogen, and danced around. I thought that I would like to make some of my own and that the best material to use for the required electrolysis was sodium hydroxide (caustic soda) which I bought from a hardware store. With the aid of a camping gas stove I was able to melt it in a metal tray (it melts at 300 degrees centigrade or thereabouts), and attach the electrodes of a low voltage DC power supply to start the process. However even at the low voltage it still drew too much current and burned out t…

hey guys i have a question that i cant work out how to calculate be great if you can help. Question: A mixture of 5.00E-3 mol of H2 and 1.00E-2 mol of I2 is placed in a 5 L container at 448 degrees C and allowed to come to equilibrium. Analysis of the equilibrium mixture shows that the concentration of HI is 1.87E-3 M. Calculate Kc at 448 degrees C for reaction H2(g) + I2(g) <-> 2 HI Cheers Hayz

Names of polyatomic ions usually end in -ite or -ate and names of ionic compounds end in the name of the anion in the compound. If the name ends in -ate how can you tell if it's a polyatomic ion or an ionic compound with a polyatomic ion as its anion other than memorizing it? Thanks. Sorry if it's a stupid question.

Is it possible to electroplate lead with a thin layer of copper, and how would one go about doing so? Thanks for any help

What common materials/elements could be the ones used in this gadget? : http://dragonet.com/fhp/ Has 8 cells to yield 12V, and only anodes are consumed in operation.

I want to know with detail (like they kill your veins then you internally bleed or something like that) what happens ingest, inhale, or come in contacted with skin these chemicals? Ammonium Nitrate Ammonium Chlorate Ammonium Perchlorate Potassium Nitrate Potassium Chlorate Potassium Perchlorate Cadmium Chlorine Fluorine White Phosphorus Arsenic Hydrogen Cyanide Mustard Gas Fill free to ask about the toxicity of other chemicals in this forum. This might belong in medicine.

this is wrong in chemistry wise can anyone explain the reason. we have added 50mL of water and then added 50mL of water to it and the reading is 98 instead of 100. why is that? excludig the erros such as some drops are still in the beaker etc ot in other words think that under perfect conditions.

Can someone tell me what's the difference in their Ionic Equations between: 0.1M NaOH added dropwise to 10 drops of Pb(NO3)2 & 1 drop of 0.1M Pb(NO3)2 added to 10 drops of 0.1M NaOH Thanks!
