Why was hydrogen called 'inflammable air ' ?
Hydrogen being a highly inflammable gas and oxygen being a supporter of combustion yet , water which is a compound made up of hydrogen and oxygen is used to extinguish fire🔥. why?
Could you please tell me why the speed of sound is more in hydrogen than in the air we breathe? It was written in my textbook that the speed of sound is much greater in hydrogen than in air. (Hydrogen: 1270m/s & Air: 330 m/s).
