Re: C2F6 + HNO3 + H2O Inquiry

There will be no reaction. But your explation I dont think so. Flourine has the highest electronegativity, so there will be a polarisation between C and H. But this makes the bonding more stronger.

Re: Photosensitive reaction

The first one is not possible. Hydrid is very reactive. The second one works. The third one will get explosion.

Re: Distillation

Instead of distillation you can buy in super market vinegar essence it has about 25 %.

Re: Salt and vinegar and penny experiment full balanced

That will do acetic acid by its own. Acetic acid is not able to create hydrochloric. Its to weak.

Cu(OH)2 + 2 CH3COOH => Cu(CH3COO)2 + 2 H2O

Chloride ion can be exchanged by the acetate

Cu(CH3COO)2 + 2 NaCl => CuCl2 + 2 CH3COONa

Re: Alkali earth metals

Why you saying there not grouped togethrr. Of course they are grouped. Alkali metal group 1 and earth alkali metal group 2 in PSE.
The difference between both groups are that the cathion of group1 is Me+1 loose 1 electron and the one of group 2 is Me+2 looses 2 electrons.

Re: I don’t understand

The reaction goes in opposit. The equilibrium is on left side 100%.

Re: Products of this reaction?

There is not really a reaction because iron is in both cases Fe-II. If one of it is Fe-III then a blue colour of prussian blue will be formed. Fe3[Fe(CN)6]2 Iron-II-hexacyanoferrate-III or Fe4[Fe(CN)6]3 Iron-III-hexacyanoferrate-II So need either K3[Fe(CN)6] or NH4Fe(SO4)2 https://en.m.wikipedia.org...

Re: Balance the equation?

It must be H2O not HZO
On the right side you see Al2(CO3)2 , so how many AlCl3 you can make
Try it from there by yourself.

Re: Chemical equilibrium composition

You have ammonia and methane on educt side already why you should have it on product side again. What kind of process is it. At least you can make from 1 mole methane 2 mole hydrogen and 1 mole carbon. Ammonia can be decomposed in the back reaction of Haber Bosch 2 mole ammonia give 1 mole nitrogen ...

Dont think so. C-F bonds are very stable. 1% is very diluted acid.

Re: ORGANIC CHEMISTRY

Dont post so many homework here,show your ideas too.

The nitrogen of pyridine will be protoned. Acetate is remaining.
