Respuesta :

C5H12 + 8 O2 → 5 CO2 + 6 H2O 

8 molecules of O2 are required.

Answer:

8 molecules of oxygen gas are required.

Explanation:

Combustion reaction is the type of chemical reaction in which a hydrocarbon reacts with oxygen gas to give to carbon dioxide and water.

[tex]C_5H_{12}+8O_2\rightarrow 5CO_2+6H_2O[/tex]

According to reaction ,1 mole of pentane reacts with 8 molecules of oxygen gas to give 5 moles of carbon dioxide and 6 moles of water.

So, to burn 1 mole of pentane we will need 8 molecules of oxygen gas.
