How do I find this out? How about Nitrogen gas (N2)?

2006-12-02 15:51:37 · 4 answers · asked by Josh 5

I just want to know if there is any way that could work. For example: a mixed stream of 50%/50% hydrogen and carbon monoxide comes from a container of heated coke when water is brought into contact with it (producer gas).

Can a vortex precipitator of the type usually used for removing dust separate the two gasses to any significant degree? Any idea how efficient this might be?

Similarly [I know, I know, this is almost a separate question] could such a vortex device separate a mixture of silica (SiO2) and alumina (Al2O3) particles in water?

Any ideas, suggestions that might work? A filter column won't work for insoluble substances, will it?

This is for an S/F story in a primitive setting with modern knowledge but without modern resources. But I want it to work right. Thanks, everybody!

It's not NH3 from what I've learned so far. CuCl2 will ppt with any soluble salt of a silver group, but will MgCl2 as well?

Question 2: I need a reagent that will form a ppt with soln of Cu(NO3)2, but not with a soln of Sb(NO3)3. All I could find here is that Cu2+ will ppt with neutral and negative ligands.

Idenify the type of Reaction & Balance these:
1) Al + O2 >>> Al2O3
2) HgO>>>>Hg + O2
3) NaOH + H2SO4>>>Na2SO4 + H2O
4) Fe + O2>>>>Fe2O3
5) Pb(NO3)2 + k2CrO4>>>>PbCrO4 + KNO3
6) H2 + N2>>NH3
7) C3H5(NO3)3>>>CO2 + N2 + H2O + O2
8) Fe + CuCl2 >>> FeCl2 + Cu
9) KCl O 3 >>> KCl + O2
10) Mg + HCl >>>H2 + MgCl2
JUST ONLY BALANCE THESE::
11) BaCl2 + H2SO4 >>> BaSO + HCL
12) P + O >>> P4 O10
13) KClO3 >>> KCL + O2
14) C3H8+ O2 >>> CO2 + H2O
15) Cu + AgNO3 >>> Cu(NO3)2 + Ag

I'n giving 5 stars if you answer all these good & all of these!
