Question

The combustion reaction of propane is described by the reaction.

Answer 1

Answer:

$\huge\boxed{\sf 5\ moles\ of\ oxygen}$

Explanation:

Chemical Reaction:

$C_3H_8+5O_2 \longrightarrow 4H_2O+3CO_2$

From the reaction, we can say that,

• 1 mole of propane and 5 moles of oxygen produce 4 moles of water and 3 moles of carbon dioxide.

So, to generate 3 mole of carbon dioxide, 5 moles of oxygen are required. (as shown in the chemical reaction!)
