Predict the products of reactions
« on: April 06, 2023, 11:08:36 AM »
1)MnCO3 (s)+ HI(aq)  :rarrow:

Answer: MnCO3 (s) +2HI(aq)  :rarrow: MnI2 (aq)+H2O(l) +CO2(g)

2)CoO (s) + O2(g) :rarrow:

Answer: 6CoO(s) +O2 (g) :rarrow: 2Co3O4(s)

3)La(s) + O2(g)  :rarrow:

Answer: 4La(s) + 3O2(g) :rarrow: 2La2O3(s)

4)V(s) + VCl4(s)  :rarrow:

Answer:V(s) + VCl4(s) :rarrow: 2VCl2(s)

5)Co(s) + xsF2(g) :rarrow:

Answer: Co (s) + xsF2(g)  :rarrow: CoFxs(s)

6)CrO3(s) + CsOH (aq)  :rarrow:

Answer:CrO3(s) + 2CsOH(aq)  :rarrow: Cs2CrO4(aq) + H2O(l)

Please note that in reaction 5), xs represents an excess of F2. The product will be a cobalt fluoride with a stoichiometry that depends on the amount of F2 used.

1. correct
2. Why no Co2O3
3.correct
4.what about with VCl3
5.what about with CoF3
6. What about with Cs2Cr2O7

CsOH suggests alkaline conditions.

CsOH suggests alkaline conditions.

And CrO3 suggest acidic condition. The question is which compound is in excess.
