Step One
Find the moles of HCl
C = 1.0 mol/L
V = 75 mL = 75 / 1000 = 0.75 L
Note the concentration is in Liters.
<em>Formula</em>
n = C*V
<em>Solve</em>
n = 1.0 * 0.075
n = 0.075 moles
Step two
Adjust the number of moles of HCl
How every mol of H2 produced, you will require 2 mol of HCl
2/1 = 0.075/x Cross multiply
2x = 0.075 Divide by 2
x = 0.075 / 2
x = 0.0375 moles of H2 <<<<<<<<< Answer

Answer: 2) see below
3) 2AgCl → 2Ag + Cl₂
<u>Explanation:</u>
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)

3) When silver chloride (solid) is exposed to sunlight, it decomposes into silver (solid) and chlorine (gas).
The equation is written as:
