CH4 + 202 → CO2 + 2H2O

Explanation:

The combustion of methane gas (CH4) can be written as followed

CH4 + O2

The Law of Conservation of Mass basically states that matter can neither be created nor destroyed. As such, we must be able to show this in our chemical reaction equations.

The combustion of methane gas is an irreversible reaction.

The products are carbon dioxide (CO2) and water (H2O)

CH4 + 02 → CO2 + H2O

Since matter can neither be created nor destroyed; on both side of thereaction we should have the same amount of elements.

On the left side we have 4 hydrogen atoms. Toget 4 hydrogen atoms on the right side weshould multiply H2O by 2

CH4 + 02 → CO2 + 2H2O

On both sides, the amount of hydrogen ( and also carbon) atoms is equal now. But, on the righ side we have 4 oxygen atoms, while, on the left side only 2 oxygen atoms. To equal this, we should multiply O2 on the left side by 2.

CH4 + 202 → CO2 + 2H2O

This is the balanced chemical equation for the combustion of methane gas

Answer from: Quest

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic
