Why concentrated nitric acid is not used to prepare hydrogen gas?
Usually an active metal displaces hydrogen acids. But Nitric Acid is a very strong oxidizing agent i.e. it leads to addition of oxygen to another substancevery quickly . Thus, when hydrogen is formed due to the addition of a metal to nitric acid, it oxidises hydrogen into water. That is why concentrated nitric acid is not used in the preparation of hydrogen gas.
What happens in the reactions of aqueous bromide ions with aqueous silver nitrate following by the addition of concentrated aqueous ammonia?
Nothing
Is potassium carbonate a element or compound?
Potassium carbonate is a compound. It consists of the elements potassium, carbon, and oxygen. The balanced chemical formula is: 2KOH + CO2 → K2CO3 + H2O which is a result of the addition of carbon dioxide to potassium hydroxide. The potassium hydroxide in this equation comes from the electrolysis of potassium chloride. Potassium carbonate is a compound. It consists of the elements potassium, carbon, and oxygen.

What are the uses of potassium?
from Encarta: Potassium metal is used in photoelectric cells. Potassium forms many compounds resembling corresponding sodium compounds, based on a valence of 1. A few of the element's most important compounds follow. Potassium bromide (KBr), a white solid formed by the reaction of potassium hydroxide and bromine, is used in photography, engraving, and lithography, and in medicine as a sedative. Potassium chromate (K2CrO4), a yellow crystalline solid, and potassium bichromate, or potassium dichromate (K2Cr2O7), a red crystalline solid, are powerful oxidizing agents used in matches and fireworks, in textile dyeing, and in leather tanning. Potassium iodide (KI), a white crystalline compound that is very soluble in water, is used in photography for preparing gelatin emulsions and in medicine for the treatment of rheumatism and overactivity of the thyroid gland. Potassium nitrate (KNO3), a white solid prepared by fractional crystallization of sodium nitrate and potassium chloride solutions, is used in matches, explosives, and fireworks, and in pickling meat. It occurs naturally as saltpeter. Potassium permanganate (KMnO4), a purple crystalline solid, is used as a disinfectant and germicide and as an oxidizing agent in many important chemical reactions. Potassium sulfate (K2SO4), a white crystalline solid, is an important potassium fertilizer and is also used in the preparation of potassium alum. Potassium hydrogen tartrate (KHC4H4O6), commonly known as cream of tartar, is a white solid used in baking powder and in medicine.
How does the addition of ADH affect the concentration of potassium in the urine?
Anti-diuretic hormone (ADH) causes water to be absorbed from the urine back into the body. Everything else in the urine, including electrolytes such as potassium, is concentrated.
