Question
In the following combustion reaction, predict the two products.
C12H26 + O2 --> _________
Solution
1. Break Down the Problem
We begin by identifying the reactants in the combustion reaction, which are a hydrocarbon () and oxygen (). Our goal is to predict the products of this combustion reaction.
2. Relevant Concepts
In a complete combustion reaction of a hydrocarbon:
- The products are carbon dioxide () and water ().
- A combustion reaction typically follows the general formula:
3. Analysis and Detail
For the complete combustion of dodecane ():
- Each carbon () atom produces one molecule of carbon dioxide ().
- Each pair of hydrogen () atoms produces one molecule of water ().
From :
- There are 12 carbon atoms, which will produce .
- There are 26 hydrogen atoms, which will produce molecules.
4. Verify and Summarize
The overall reaction should balance with respect to the number of each type of atom. Therefore, we will also need to calculate the amount of required.
The balanced equations can be summarized as follows:
To determine the number of molecules required, we calculate:
- From the products, there are oxygen atoms in and oxygen atoms in .
- This gives a total of oxygen atoms needed.
- To find how many we need, we divide by 2: molecules of .
Final Answer
The balanced equation is:
Thus, the two predicted products are (carbon dioxide) and (water).
