Answer:
Hehehe :)
Interesting.
Phase 1.
Zinc heated in Air
2Zn + O₂ = 2ZnO
Zinc Oxide is formed.
SOLID A = (ZnO)ZINC OXIDE
Phase 2.
Zinc Oxide is heated with Powdered Magnesium.
magnesium would displace Zinc since its higher in the series.
ZnO + Mg = MgO + Zn
SOLID B + SOLID C = MgO(Magnesium Oxide) + Zn(Zinc metal)
At Phase 3...( 1st Aspect)
Both MgO and Zn can react with Dilute HCl.
Now the products required from the question are a "SOLUTION D" AND "GAS E".
When MgO reacts with Dilute HCl
The products are
MgO + 2HCl = MgCl₂ + H₂O
Now H₂O could be steam(gas) or Water :(
This is a little Uncertain.
But if we use Zn as the one reacting with Dilute HCl
We have
Zn + 2HCl = ZnCl₂ + H₂
Now I'll go with this cos H₂ is simply Hydrogen Gas.
SOLUTION D + GAS E = ZnCl₂(Zinc Chloride) + H₂(Hydrogen Gas)
2nd aspect of Phase 3 ( or denominator)
ELECTROLYSIS OF MOLTEN B
B = MgO
MOLTEN B = MOLTEN MAGNESIUM CHLORIDE.
From Electrolysis of MgO
Mg²⁺ + 2e- = Mg
2O²⁻ = O₂ + 2e⁻
Combining Both Equations.
Mg²⁺ + 2O²⁻ = 2Mg(ₛ) + O₂(g)
Magnesium is a Silvery Metal :)
and Oxygen is a Gas.
Wow!!!
So this automatically makes "SILVERY METAL F" AND "GAS G" TO BE MAGNESIUM AND OXYGEN RESPECTIVELY.
SILVERY METAL F = MAGNESIUM
SILVERY METAL F = MAGNESIUMGAS G = OXYGEN
All the way down to phase 5 now.
Hope you're with me?
Now CuSO₄ is added to Mixture of Mg and O₂. Oxygen would prolly escape into the atmosphere
Leaving Mg to react with CuSO₄
Mg + CuSO₄ = MgSO₄(aq) + Cu(s)
Copper when precipitated from solution sometimes has Brown Pink Color.
MgSO₄ is Solid.
Niceeeee
That's exactly what they need as the answer.
Automatically...
BROWN PINK SOLID H = COPPER(CU)
SOLUTION I = MgSO₄(MAGNESIUM SULPHATE)
Hope this Helps :)
Have a great day.
