Question

prove that hydrogen on combustion in air forms water​

Answer 1

Answer:

Test-tubes containing three different proportions of hydrogen and air are prepared and the gas mixtures ignited. The loudness of explosions (‘pops’) is noted and related, at least in part, to the amount of energy produced when the hydrogen is burnt. The mixture producing the loudest ‘pop’ is used to estimate the ratio in which hydrogen and oxygen combine.
