Answer:
757.5 kPa
Explanation:
Boyle's law states that p1 * v1 = p2 * v2
v1 = 12 mL
v2 = 8 mL
p1 = 505 kPA
p2 = ?
(505)(12) = (p2)(8)
6060 = (p2)(8)
p2 = 757.5
Answer:
Hydrocyanic acid.
Explanation:
Hydrocyanic acid or hydrogen cyanide is also known as formonitrile (HCN), it is a colorless, extremely poisonous liquid (because it inhibits cellular oxidative processes) which is having boiling point 26 °C, freezing point -14 °C, and highly volatile in nature.
The solution of hydrogen cyanide in aqueous is known as Prussic acid or Hydrocyanic acid. Hydrogen cyanide is used for many chemical processes such as fumigation, the concentration of ores, the case-hardening of steel and iron.
Answer:
28 g solute per 100 g of solution
Explanation:
28% mass means that in all your solution you have 28% of your solute, you could use grames/grames, ml/ml or whatever you want to. So if you are working with a 100 grams solution, 28 grams of that solution must be solute if you want a 28% mass. So, the correct answer is 28 g solute per 100 g of solution.
