(a) 20cm of a gaseous hydrocarbon M required 150cm of oxygen for complete
combustion. M reacts with one mole of hydrogen gas in the presence of nickel
catalyst to give the hydrocarbon N.
(1) What is the molecular formula of hydrocarbonM
Write the reaction of the hydrocarbon M with hydrogen
Write all isomers of the hydrocarbon N and their IUPAC names
(iv) Giving reason, arrange these isomers in order of increasing boiling point.​

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
