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

Sagot :

Answer: 10.84 moles of [tex]CO_2[/tex] will be produced from complete combustion of 5.42 moles of ethanol

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

[tex]2C_2H_6O+7O_2\rightarrow 4CO_2+6H_2O[/tex]  

According to stoichiometry :

2 moles of ethanol produce =  4 moles of [tex]CO_2[/tex]

Thus 5.42 moles of ethanol will produce=[tex]\frac{4}{2}\times 5.42=10.84moles[/tex]  of [tex]CO_2[/tex]  

Thus 10.84 moles of [tex]CO_2[/tex] will be produced from complete combustion of 5.42 moles of ethanol
