CH₄ +2O₂  →  CO₂ +2H₂O 
How many atoms are there on the left side of the equation compared to the right side? 

• The left side has more atoms than the right side. 
• The right side has more atoms than the left side. 
• The left and right side have the same number of atoms. 
• It is impossible to know because it depends on the reaction speed.
