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.

CsOH suggests alkaline conditions.

CsOH suggests alkaline conditions.

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