I can't find it quickly any more. However. We cannot (from a chemical point of view) reduce the rubber to its carbon content, then it would be pure carbon and then we can/have to treat him as such. So the calculation using stoichiometry is certainly correct, even if the following statement is perhap...

I'm sorry, I have to come back to this calculation again. I read somewhere that the factor between C5H8 and CO2 after burning is 3,66. I think I know why: Before we found that "(C5H8 with 68.1170 g/ mol ) leads to 5 * 44g => 220 g CO2 and 4 * 18 = 72 g H2O .1 kg contain 14,7 mol Isoprene this w...

Thanks again !!

Hi Chen, Thanks a lot for this introduction. I found this on a website of a natural rubber supplier: "When considering the macrostructure of natural rubber, one must note the very high molecular weight of natural rubber. With a molecular weight range of from 3 x 104 to 1 x 107, it is several ti...

Hi , I can easily derive on formula basis what happens if polyisoprene is burned: C5H8+7O2→5CO2+4H2O. I also can use this tool on webqc()org to get the atomic weight. But how to get a conclusion for "non-chemists" like one litre Diesel emit 2640 grammes of CO2/l. If I have 1 kg of rubber (...
