Question
given the balanced equation:
2Al2O3(s)-->4Al(s)+302(g)
What is the total number of moles of O2 that are produced when 8.0 mol of Al2O3(s)are totally decomposed ?
please help me.

Answers
2Al2O3(s)-->4Al(s)+302(g)
From the equation 2 moles of Al2O3 yields 3 moles of O2
so
From the equation 4 moles of Al2O3 yields 6 moles of O2
so
From the equation 8 moles of Al2O3 yields ?? moles of O2

From the equation 8 moles of Al2O3 yields ?? moles of O2
so the answer is 2 moles ?
i meant 12* moles
wait is it 24 moles ?
Are you just guessing? Which answer are you going for and why?
It's 12 moles. Cross multiply 8x6= 48, and then 48/4= 12
