Wind, air that moves to the ground
Answer:
b. 6.02 x 1023 molecules
Explanation:
The formula mass of ammonia is 14 + 1 × 3 = 17.
The number of moles in 27.6g ammonia is 27.6 ÷ 17 = 1.62 mol.
A mole is 6.02 × 10²³, so the number of hydrogen atoms in a 1.62 moles of ammonia is 1.62 × 6.02 × 10²³ × 3 = 2.93 × 10² atoms.
Ammonium perchlorate appears as a white, crystalline solid or powder. Classified as a division 1.1 explosive if powdered into particles smaller than 15 microns in diameter or if powdered into larger particles but thoroughly dried. Does not readily burn, but will burn if contaminated by combustible material. May explode under prolonged exposure to heat or fire. Used to make rocket propellants, explosives, pyrotechnics, as an etching and engraving agent, and in analytical chemistry.
The mixture of phenol and benzoic acid is separated by adding to produce brisk effervescence with sodium benzoate .
When benzoic acid react with then sodium benzoate is produced which is soluble in water and separated from non aqueous solvent . Organic compounds are soluble in organic solvent and inorganic compound mainly soluble in inorganic solvent like water.
What is brisk effervescence?
Brisk effervescence is when continuous gas evolution occurs in a chemical reaction like CO2. When HCl is added in then CO2 evolved.
