Write a balanced equation for the complete combustion of methane, CH4

Question

aaronq · Answer

methane + oxygen gas $\rightarrow$ carbon dioxide + water + energy

whpalmer4 · Answer

@karlz_jo aaronq has sketched out the components of the combustion reaction, but that is not yet a balanced equation.  You need to expand on it to show the physical state of each reactant and product, and indicate the number of each atom or ion involved.

An example for the combustion of hydrogen and oxygen to form water:

$$2H_2(g)+O_2(g) \rightarrow 2H_2O(l)$$
the states of each reactant and product are shown, and the number of atoms balances across the reaction arrow.  2*2=4 H atoms on the left, 2*2=4 on the right. 2 O atoms on the left, 2 on the right.
