(1) These included methane, ammonia, probably hydrogen cyanide, hydrogen sulphide and carbon monoxide.

(2) Smoke contains benzene, nitrosamines, formaldehyde and hydrogen cyanide.

(3) Ammonia and hydrogen cyanide are both thermodynamically favored species.

(4) When the seeds of cherries are crushed, chewed, or even slightly injured, they produce prussic acid (hydrogen cyanide).

(5) Carbon monoxide and hydrogen cyanide are examples of chemical asphyxiants.

(6) The addition reaction with hydrogen cyanide is base - catalysed.

(7) The addition of steam inhibits the production of hydrogen cyanide.

(8) Increasing the system pressure increases the concentration of ammonia and hydrogen cyanide.

(9) The Chinese government says that Japan left some 2 million chemical munitions —shells, bombs and barrels of deadly agents such as mustard gas, phosgene(Sentencedict), hydrogen cyanide and lewisite.

(10) If a cherry pip is chewed, crushed , or somehow damaged , it automatically produces hydrogen cyanide.
