Problem: Gasoline is composed primarily of hydrocarbons, including many with eight carbon atoms, called octanes. One of the cleanest-burning octanes is a compound called 2,3,4-trimethylpentane, which has the structural formula shown in the figure . The complete combustion of one mole of this compound to CO2 (g) and H2O(g) leads to HH = -5064.9 { m kJ/mol}.Write a balanced equation for the combustion of 1 mol of C8H18 (l).

FREE Expert Solution

We're being asked to write the combustion reaction for 2,3,4-trimethylpentane acid, C8H18 (l)

Recall that in combustion analysisa compound reacts with excess O2 to form products

For a compound composed of C and H the reaction looks like this:

CxHy + O2 (excess) x CO2 + y H2O

We will do the following steps:

Step 1: Write the chemical reaction

Step 2: Balance the chemical reaction
