LIMITING REACTANT! Last one please help!!

Al

Explanation:

You divide the moles by the coefficient to find which one is the limiting reactant. Whichever result is lower, that's the limiting reactant.

Observe:

There were 2 moles of Al in the reaction and the coefficient behind Al is 2 - 2/2 = 1

There were 6 moles of H2O in the reaction and the coefficient behind H2O is 3 - 6/3 = 2

Since the result for Al is lower, that's the limiting reactant.

what are the choices?

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
