Using the balanced chemical equation below. 2Al2O3 --> 4Al + 3O2 How many moles of oxygen are produced if 11.0 mol of Al are produced?

8.25 moles of oxygen will be produced.

Explanation:

Given a balanced chemical equation;

2Al₂O₃ ------> 4Al + 3O₂

from the balanced chemical equation above, 3 moles of Oxygen are produced when 4 moles of Aluminum are produced.

4 moles of Al --------> 3 moles of Oxygen

11 moles of Al --------> ?

Therefore, 8.25 moles of oxygen will be produced.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
