Can someone check my answer? The question is: In order for the reaction 2Al(s) + 6HCl(aq)-> 2AlCl3(aq) + 3H2(g) to occur, which of the following must be true?
a. Al must be above Cl on the activity series.
b. Al must be above H on the activity series.
c. Heat must be supplied for the reaction.
d. AlCl3 must be a precipitate.
It was between a or b and I believe it is b. Thanks

B it is. Look at the reaction. It is a single replacement. What is it replacing? It is replacing H; therefore, it must be above H and where it is with respect to Cl is immaterial.
