Answer:
The given reaction is combustion reaction heat is also produced.
Step-by-step explanation:
Chemical equation:
CH₄ + 2O₂ → CO₂ + 2H₂O
The given reaction is combustion of methane. When methane burn it produced water and carbon dioxide. Heat is also produced.
The given reaction followed the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
CH₄ + 2O₂ → CO₂ + 2H₂O
There are equal number of carbon hydrogen and oxygen atoms present on both side of equation. So it follow the law of conservation of mass.
