1. Give the names of each of the following a) KBr b) HCl c) KMnO d) \( \mathrm{NO}_{2} \) e) \( \mathrm{NH}_{4} \mathrm{OH} \) f) \( \mathrm{Na}_{2} 30_{4} \)

a) KBr is known as Potassium Bromide, a compound often used in the pharmaceutical industry and as a photographic chemical. b) HCl is Hydrogen Chloride, commonly known as Hydrochloric Acid, a strong acid used in various industrial processes and cleaning products. c) KMnO is Potassium Manganate, which plays a crucial role in oxidation-reduction reactions in laboratories. d) \( \mathrm{NO}_{2} \) is Nitrogen Dioxide, a significant pollutant that contributes to smog and respiratory problems in city environments. e) \( \mathrm{NH}_{4} \mathrm{OH} \) is Ammonium Hydroxide, a diluted solution of ammonia in water, widely used as a cleaner and in the food industry as a pH regulator. f) \( \mathrm{Na}_{2} 30_{4} \) appears to be a typographical error. If you meant \( \mathrm{Na}_{2} \mathrm{SO}_{4} \), that’s Sodium Sulfate, an important compound in detergents, paper, and glass manufacturing.
