Faraday's second law: When same charge is passed, masses deposited are proportional to: MCQ with Answer and Explanation

Explanation:
The Ostwald process is the industrial method for manufacturing nitric acid (HNO₃). It involves the catalytic oxidation of ammonia (NH₃) to nitric oxide (NO), which is then further oxidized to nitrogen dioxide (NO₂) and absorbed in water to form concentrated nitric acid.

Explanation:
Teflon is polytetrafluoroethylene (PTFE) polymerized from tetrafluoroethene (CF₂=CF₂). CH₂=CH₂ gives polythene; CH₂=CHCl gives PVC; CH₂=CH-C₆H₅ (styrene) gives polystyrene. The C-F bond is extremely strong, giving Teflon its chemical inertness and thermal stability.

Explanation:
UV irradiation uses ultraviolet light to disrupt the DNA of microorganisms, rendering them unable to reproduce and cause disease. It is a physical disinfection method, leaving no chemical residue. Chlorination uses chlorine, ozonation uses ozone, boiling uses heat.
