Question

How many moles of carbon dioxide are produced from the complete combustion of 5.42 moles of ethanol? 2C2H6O +7 O2 ®4 CO2 + 6H2O

Answer 1

Answer: 10.84 moles of
`CO_2` will be produced from complete combustion of 5.42 moles of ethanol

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
`6.023* 10^(23)` of particles.

`2C_2H_6O+7O_2\rightarrow 4CO_2+6H_2O`

According to stoichiometry :

2 moles of ethanol produce = 4 moles of
`CO_2`

Thus 5.42 moles of ethanol will produce=
`(4)/(2)* 5.42=10.84moles` of
`CO_2`

Thus 10.84 moles of
`CO_2` will be produced from complete combustion of 5.42 moles of ethanol
