struggling to find balanced chemical reaction

[xxxy]

What would be the balanced chemical reaction if NiSO₄.6H₂O reacted with LiOH.H₂O and (NH₄)₂S₂O₈ in the presence of H₂O (as the solvent of the solution is H₂O and heat? I am struggling to find a balanced chemical reaction.

It will only a precipitation of Ni(OH)₂ take place.
Ammonium will release Ammonia.

Thank you for the response. Wouldn't the reaction look like:

NiSO₄.6H₂O + (NH₄)₂S₂O₈+2LiOH.H₂O+H₂O -> LiNiO₂+LiHSO₄+(NH₄)₂SO₄+H₂SO₄?

If not, what would be the actual chemical reaction?

Can you read what I wrote?
Ni 2+ + 2 OH- => Ni(OH)₂
And NH₄+ + OH- => NH₃ + H₂O
I dont think S₂O₈ 2- is strong enough to oxidise Ni in an aqueous solution as you wrote.

Maybe in a melted form it would be different

Ni 2+ + 4 OH- => NiO₂- + 2 H₂O + e-

S₂O₈ 2- + 2 e- => 2 SO₄ 2-
