Answer:
Benzoyl Chloride
Explanation:
Friedel-Craft Acylation is reaction utilized to add electrophiles (particularly carbonyl group) across double bonds of aromatic compounds.
In given case benzophenone is synthesized using benzene and benzoyl chloride.
Mechanism:
Step 1: In first step benzoyl chloride is treated with lewis acid to generate an electrophile i.e. oxo(phenyl)methylium.
Step 2: In the second step benzene undergoes electrophilic substitution reaction and adds the electrophile.
Step 3: In last step the aromaticity of benzene is restored with the elimination of proton.

Answer:
8.5 mol H₂SO₄
Explanation:
It seems the balanced reaction the problem is referring to is absent, however the description matches the following balanced reaction:
- 2SO₂ + O₂ + 2H₂O → 2H₂SO₄
Now we <u>can convert 8.5 moles of SO₂ into moles of H₂SO₄</u>, using <em>the stoichiometric coefficients of the balanced reaction</em>:
- 8.5 mol SO₂ *
= 8.5 mol H₂SO₄
