What properties would have caused early researchers to name hydrogen "inflammable air”

It ignited in air to form water

Explanation:

In the experiments of Cavendish, he discovered a gas lighter than air when he added certain metals to dilute acids. The gas when breathed is significantly different from air.

The gas is known to burn in air when it approaches a flame to form water hence the name 'inflammable air' was given to the gas. It was later called hydrogen which means 'water former'.

b) mutualism

hope this : )

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
