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
