What volume of #H_2(g)# is produced when 2.00 g of #Al(s)# reacts at STP?
We ASSUME that the aluminum reacts with EXCESS
And so we address the redox reaction....
And so the reaction should produce
(this is actually a little bit too much to collect in an upturned graduated cylinder!).
*what are standard conditions? You got me...they are all over the place these days....I know of THREE definitions in THREE national curricula...for God's sake!
You're probably referring to the reduction-oxidation reaction of aluminum metal in aqueous acid,
Assuming that our acid is in excess,
of hydrogen gas will be evolved from the reaction vessel.
