Which of the following gases is responsible for the greenhouse effect? MCQ with Answer and Explanation

Explanation:
H₂SO₄ is used in production of fertilizers, detergents, dyes, explosives, petroleum refining, and many other chemicals. Its wide industrial use earns it the title. It's not the strongest (e.g., HClO₄ is stronger).

Explanation:
Faraday constant (F) = 96485 C/mol, approximately 96500 C/mol. It is the magnitude of electric charge per mole of electrons. Charge on one electron = 1.602 × 10⁻¹⁹ C, multiplied by Avogadro's number gives F. Used in electrolysis calculations: mass deposited = (Q × M)/(n × F).

Explanation:
Lead-acid batteries use dilute sulfuric acid (approx 35%). During discharge, H₂SO₄ concentration decreases, forming PbSO₄ on both electrodes.
