I have absolutely no idea, but if you go in the math chat and ask for help, sometimes ppl will respond. You know. People who actually know pellet. ;)

Answer 2

Complete combustion (given sufficient oxygen) of any hydrocarbon produces carbon dioxide and water.
Construct a balanced equation
CH4+O2-->CO2+H2O
Write down the number of atoms that you have on each side of the equation.
On the reactant Side: 1 C, 4 H, 2 O
On the product side: 1 C, 2 H, 3 O
Start by adding coeffcient to balance both sides
