How to write the equation for the combustion of ethane C2H6?

react with O2, products CO2, and H2O

then balance it.

To write the equation for the combustion of ethane (C2H6), you need to know that combustion is a chemical reaction between a fuel and oxygen that produces carbon dioxide and water vapor as the main products. Follow these steps to write the equation:

Step 1: Determine the reactants:
The reactants in the combustion of ethane are ethane (C2H6) and oxygen (O2).

Step 2: Write the unbalanced equation:
C2H6 + O2 ->

Step 3: Balance the carbon atoms:
Count the number of carbon atoms on both sides of the equation. In C2H6, there are two carbon atoms, so we need 2 carbon dioxide (CO2) molecules on the product side.

C2H6 + O2 -> 2CO2

Step 4: Balance the hydrogen atoms:
Count the number of hydrogen atoms on both sides of the equation. In C2H6, there are six hydrogen atoms, so we need 3 water (H2O) molecules on the product side.

C2H6 + O2 -> 2CO2 + 3H2O

Now, the equation is balanced with equal numbers of carbon and hydrogen atoms on both sides.

The balanced equation for the combustion of ethane is:
C2H6 + O2 -> 2CO2 + 3H2O
