Remember, when working with combustion reactions the products are almost ALWAYS
CO2 + H2O.
Your equation should now be:
CH4 + 2 O2 -> CO2 + 2 H2O
Note: this equation is balanced
If we’re talking about combining Nitrogen and Hydrogen in a reaction, it would synthesize to form ammonia (NH3)
The chemical equation for that would be:
N2 + H2 -> NH3
Balanced chemical equation:
N2 + 3 H2 -> 2 NH3
(If you’re wondering where the 2’s come from in N2 and H2, it’s because they are known as diatomic elements.
Diatomic elements are:
Hydrogen
Oxygen
Bromine
Fluorine
Iodine
Nitrogen and
Chlorine
•To make it easier to memorize remember the acronym, HOBrFINCl.
•When these elements are seen individually in a chemical equation the 2 at the bottom (aka subscript) is placed.
Hope this helps. If you have any questions please let me know in the comments.
