Question

An ordered list of chemical substances is shown:

Answer 1

Answer : The correct option is, (B) 2, 3 and 6.

Explanation :

Combustion reaction : It is a type of reaction where a hydrocarbon react with an oxygen molecule to give carbon dioxide, water as a product.

In general,

$Hydrocarbon+O_2\rightarrow H_2O+CO_2$

For example : Ethane react with oxygen to give carbon dioxide and water.

$C_2H_8+4O_2\rightarrow 2CO_2+4H_2O$

In the given list, $O_2$ is a reactant and $CO_2,H_2O$ are the products.

Therefore, the correct answer is, (B) 2, 3, and 6
