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 onds are very stable. 1% is very diluted acid.

Re: BALANCE CHEMICAL EQUATIONS

Acid + Base gives salt + water. So it depends how much from each is added what happend. Like KOH + H3PO4 you can have 3 different results. KH2PO4, K2HPO4 and K3PO4. Ammonia gives Ammonium NH4+ Urea decompose with acids to ammonia and carbondioxide. Salt1 + acid1 gives Salt2 + acid2, in solution you ...
