Question

H

Answer 1

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.
