Question

Suppose you have 6 miles of ethanol(C2H6O)to combust.How many moles of oxygen will the combustion use?

Answer 1

Answer: 18 moles of oxygen will be used.

Step-by-step explanation:

Combustion is a chemical reaction in which a hydrocarbon is oxidized in the presence of oxygen to give carbon dioxide and water.

The balanced chemical reaction for combustion of ethanol is:

`C_2H_6O+3O_2\rightarrow 2CO_2+3H_2O`

According to stoichiometry :

1 mole of ethanol require = 3 moles of
`O_2`

Thus 6 moles of ethanol will require=
`(3)/(1)* 6=18moles` of
`O_2`

Thus 18 moles of oxygen will be used.
