Question

C3h8 + 5 o2 --> 3 co2 + 4 h2o this is an example of a _______________.

Answer 1

Answer:
combustion reaction

Explanation:
In chemistry, a combustion reaction is defined as a reaction between an oxidant and any compound that leads to the production of another compound along with a huge amount of heat.

Now, let's check the reaction given:
C₃H₈ + 5 O₂ --> 3 CO₂ + 4 H₂O
The oxidant is oxygen gas
The compound reacting is propane
The compound produced is carbon dioxide along with water vapor and heat

Therefore, the given reaction is a combustion reaction

Hope this helps :)

Answer 2

Answer: $C_{3}H_{8} + 5O_{2} \rightarrow 3CO_{2} + 4H_{2}O$ this is an example of a combustion reaction.

Explanation:

A reaction in which a compound reacts with oxygen and results in the formation of carbon dioxide and water is known as combustion reaction.

For example, $C_{3}H_{8} + 5O_{2} \rightarrow 3CO_{2} + 4H_{2}O$ is a combustion reaction.

Also, it is known that combustion reactions are exothermic in nature because heat is released during these reactions.
