Ethanol can be converted to ethanoic acid by: MCQ with Answer and Explanation

Explanation:
Soap is made by saponification of triglycerides (fats/oils) which are esters of glycerol and long-chain fatty acids (e.g., stearic, palmitic, oleic). The sodium salt gives hard soap, potassium gives soft soap. The long hydrocarbon chain (hydrophobic) and carboxylate head (hydrophilic) provide cleaning action via micelle formation. Synthetic detergents are usually sodium salts of sulfonic acids or sulfate esters.

Explanation:
Biofertilizers are living microorganisms that enrich the soil quality. Rhizobium is a symbiotic bacterium found in the root nodules of leguminous plants that fixes atmospheric nitrogen. Urea, NPK, and ammonium sulfate are chemical fertilizers synthesized through industrial processes.

Explanation:
An ideal gas is a theoretical gas that perfectly obeys the ideal gas equation (PV=nRT) and all gas laws under all conditions. It assumes no intermolecular forces and zero molecular volume. Because of these assumptions, an ideal gas cannot be liquefied, unlike real gases which deviate at high pressures.
