Stoichiometric Combustion Calculator for Alkane, Alkene and Alkyne fuels

Given Combustion Process for Alkane fuels is,

`C_nH_(2n+2)+ar(O_2+3.76 N_2)=aCO_2+bH_2O+cN_2`

Now here `n=a` , `2n+2=2bimpliesb=n+1` and `ar=a+b/2=n+(n+1)/2=(3timesn+1)/2`

Again Combustion Process for Alkene fuels will be,

`C_nH_(2n)+ar(O_2+3.76 N_2)=aCO_2+bH_2O+cN_2`

Here `n=a` , `2n=2bimpliesb=n` and `ar=a+b/2=n+n/2=(3timesn)/2`

And Combustion Process for Alkyne fuels will be,

`C_nH_(2n-2)+ar(O_2+3.76 N_2)=aCO_2+bH_2O+cN_2`

In this case `n=a` , `2n-2=2bimpliesb=n-1` and `ar=a+b/2=n+(n-1)/2=(3timesn-1)/2`

    else
