Answer 1

Answer: 2) see below

3) 2AgCl → 2Ag + Cl₂

Step-by-step explanation:

2)

Step 1: Crushing & Grinding CuFeS₂(s)→ CuFeS₂(s)

Step 2: Froth Flotation CuFeS₂(s)----> CuFeS₂ (l)

Step 3: Roasting 2CuFeS₂(l) + 3O₂(g) → 2FeO(s) + 2CuS(s) + 2SO₂(g)

Step 4: Converting matte to blister Cu₂S(l) + O₂(g) → 2Cu(l) + SO₂(g)

Step 5: Anode Casting Cu(l) → Cu(s)

Step 6: Electrolytic Refining Cu(s) → Cu(s)

Anode: Cu(s) → Cu₂ + (aq) + 2e-

Cathode: Cu2 + (aq) + 2e- → Cu(s)

see diagram below for illustration of steps

3) When silver chloride (solid) is exposed to sunlight, it decomposes into silver (solid) and chlorine (gas).

The equation is written as:
`2AgCl_((s))\xrightarrow{\text{sunlight}}}2Ag_((s))+Cl_(2(g))`
