The reactant [tex]O_{2}[/tex] is limiting if we begin with 9. 50 grams of al and 9. 50 grams of [tex]O_{2}[/tex] .
The reactant whose number of moles is present in less quantity is called limiting reactant .
Calculation,
Given mass of Aluminium and oxygen
Mass of Aluminium = 9. 50 grams
and Mass of oxygen = 9. 50 grams
Number of moles of aluminium = given mass / molar mass of aluminium
Number of moles of aluminium = 9. 50 grams/ 26.99 = 0.351 mole
Number of moles of oxygen = given mass / molar mass of oxygen
Number of moles of oxygen = 9. 50 grams/ 31.999 = 0.296 mole
The reactant [tex]O_{2}[/tex] is limiting because oxygen present in less quantity or in limiting quantity and consume rapidly.
Therefor , the reactant [tex]O_{2}[/tex] is limiting if we begin with 9. 50 grams of al and 9. 50 grams of [tex]O_{2}[/tex] .
