Answer:
CH₄ + 2O₂
→ CO₂
+ 2H₂O
Explanation:
This kind of reaction in which a hydrocarbon combines with oxygen gas is a combustion reaction. They are mostly used to produce heat energy that can be transformed into other forms of energy.
Every chemical reaction is made up of reactants and products. The combining species on the left hand side are the reactant and the products are the result of the combination.
Note: in writing chemical equations, the state of matter must always be included.
Reactants : Methane gas CH₄
Oxygen gas O₂
Product: Carbon dioxide CO₂
Water vapor H₂O
CH₄ + 2O₂
→ CO₂
+ 2H₂O

Density is intensive because it is the ratio of two extensive properties that is mass to volume.
<h3>What is Density ?</h3>Density is defined as mass per unit volume. S.I unit if density is kg/m³.
It is expressed as
Density = or
Intensive property is the property which does not depend on the size of the system. Intensive property can be easily identified. Intensive property is the independent property. The size does not change in this.
Example of intensive property are Density, Freezing point, melting point, colour, Lustre, etc.
<h3>What is Extensive property ?</h3>Extensive property is the property which depend on the substance. Extensive property cannot be easily identified.
Example of extensive property length, weight, volume, mass etc.
Thus from the above conclusion we can say that Density is intensive because it is the ratio of two extensive properties that is mass to volume.

Disclaimer: The given question is incomplete on the portal. Here is the complete question.
Question: The density (d) of a substance is an intensive property that is defined as the ratio of its mass (m) to its volume (v)
density = or
Considering that mass and volume are both extensive properties, explain why their ratio, density is intensive.
