Question

What volume of oxygen is
required to completely burn a mixture of 224 cm3
of methane and 112 cm3 of hydrogen at S.T.P. to
produce steam and carbon dioxide ? If the steam
formed is condensed to water, find the mass of water
so formed.​

Answer 1

Answer:

therefore, 112cm cube of hydrogen will require 56cm cube of oxygen for complete combustion and thereby form 112 cm cube of steam. therefore, total volume of oxygen needed 4 burning CH4 a4H2 = 448+56=504 cm cube and total volume of steam formed =448+112=560 cm cube.
