Write the word and chemical equation for the following: Hexane undegoes complete combustion. I'm not sure at all how to do this one. I know that for compelte combustion, the products have to be H2O + O, but I don't know the formula for Hexane.

It's difficult to know how to answer a question that is so broad. Tackle for what? What do you want to accomplish? Here is the CO equation under incomplete combustion. 2C5H12 + 11 O2 ==> 10CO + 12H2O Under complete combustion: C5H12 + 8O2 ==> 5CO2 + 6H2O

Lysine, an essential amino acid in the human body, contains C,H,O, and N. In one experiment, the complete combustion of 2.175g of lysine gave 3.94g CO2 and 1.89g H2O. In a separate experiment, 1.873 g of lysine gave 0.436 g NH3. (a) Calculate the empirical formula of lysine (b...

We can only calculate the empirical formula, which is the simplest ratio between the number of atoms of the constituents. This ratio may or may not be a sub-multiple of the actual formula. We will first decide on the processes. The complete combustion means that the limiting ...
