H19

Postby Ricky Ma DIS 4E » Fri Oct 05, 2018 10:20 pm

Aspartame (C14H18N2O5) is a solid used as an artificial sweetener. Its combustion produces carbon dioxide gas, liquid water, and nitrogen gas.

I thought that combustion only releases Co2 and H20, why is there another product N? Isn't the standard rule for combustion you add oxygen and the products are always H20 and C02?

You're right, but I think because the aspartame has nitrogen in it, the gas needs to escape as a product somehow. I think that in general, all combustion reactions have CO2 and H2O as products, but might sometimes include other products to make up for any elements in the reactant that is not hydrogen, oxygen, or carbon.

Adding on to what Chathuri said, just because combustion reactions always produce CO2 and H2O, it does not mean it is limited to producing only those compounds. It means it must product those, but if there are other elements involved such as aspartame, N2 is also going to be produced separately.

Just to follow up. CO2 and H2O will be the only products of the material that is combusted only contains carbon, hydrogen, and oxygen. If it were to contain nitrogen, for example, the combustion would also produce N2.
