The product formed when ethanol reacts with ethanoic acid in presence of concentrated H₂SO₄ is: MCQ with Answer and Explanation

Explanation:
In an electrochemical cell, reduction (gain of electrons) always occurs at the cathode, regardless of whether the cell is electrolytic or galvanic. At the anode, oxidation (loss of electrons) occurs. Memory aid: 'RED CAT' (REDuction at CAThode), 'AN OX' (OXidation at ANode). In electrolysis, the cathode is connected to the negative terminal of the battery, attracting cations which get reduced.

Explanation:
Ostwald process: Catalytic oxidation of NH₃ with air over a platinum-rhodium gauze catalyst at ~800°C to form NO, then NO₂, finally absorbed in water to give HNO₃. Fe is Haber catalyst for NH₃. V₂O₅ is for SO₂ oxidation. Ni for hydrogenation. Pt-Rh alloy gauze provides high surface area and mechanical strength, reducing cost. Nitric acid is used in fertilizers (ammonium nitrate), explosives, and nitration.

Explanation:
CNG (Compressed Natural Gas) is primarily methane (CH₄). LPG is propane and butane. Methane is the simplest hydrocarbon.
