what indicator did you use

pvc is probably the best but sewer piping would work pretty good and flexible and not too expensive.

lol sorry Ill clean it i was kinda hurrying through it.

Here is a simple hood design, which Is composed of a cardboard shoe box. One can take the front and back and cut them out so the box now resembles a tube a tube. THen you add 2 computer fans in the back so that when you apple current from an adapter to the fans, they will blow air outwards and suck [fumes] in. The device is then placed in a window, and then the experiment is set in front of the "hood" intake. It worked really good for me. Adding a switch and stuff makes it work nicer, and adding a board to cover up the rest of the open window also helps.This is just an example of what you can make.

The smells could be due to the acid vaporizing from the heat of the reaction. HCL and Al is very violent and stinky.

does liquifying a gas via pressure, not cold, cause it to go cold just because it turns liquid? not counting evaporation

Id say no, because the COOH isnt removed as CO2 but it goes to a H+ and a R-COO-. So it doesnt turn into CO2 so i guess its not a decarboxylation.

Its also very corrosive, after time it tends to corrode caps. My teacher at school spilled some because over a few years the bromine ate away at the seal.

temperature and pressure are directly related

If he didnt seal it ffrom air well enough, surely it culd have absorbed something from the air- moisture perhaps? just a guess

It would seem the stuff would be well trapped in the pores. You wont be able to get all the stuff out for sure and eventually you would need to replace it.

lol and same for old granny's like mine.. ughh

any gas will occupy the same space as another at the same conditions. CO2 Ethane and Chlorine at stp will take up the same volume.

when it is like 100 degrees F outside (just about body temp) you feel hot instead of feeling perfect since its the same temperature outside as in your body?

the iron formed long before the oxygen appeared, it formed wen some stars died. ANd also, the oxide layer/crust protects it from further oxidztion.

kno3 + charcoal, sulfur, sugar or any combo of those is often used in simple rockets. More powerful rockets use Ammonium Perchlorate and aluminum with a rubber binder as propellant. ANd the most complex rockets use liquid oxygen and hydrogen, H2O2, and sometimes nitrous oxide as oxidizers. For begginers kno3 is probably the way to go.

lead paints actaully contain the lead salts like lead iodide. So if you were to burn it id say most of it would go in the ash. As long as you wash ur hands you should be fine i think.

Well, he said the bromate could be toxic. During the reaction is any elemental bromine formed or is all just oxidized to ions?

If u make your fuel putty like material or use a binder (which makes the propellant hard) or make it into "candy" it wont collapse.

as a hint, figure out how much of the organic compound and Cl2 would be needed to make the products- how much, O, C, H, and CL.

ya it has to look cool tho

distill it?

guess i was wrong

For school i have to demo 2 decomposition reactions that look "cool". Since these ppl are newbie chemists they will only be impressed with stuff such as H2O2 with soap decomposing and NI3. ANy other ideas?' Edit: dumb me- i accidentally called the tittle combustion reactions
