Question

what volume of hydrogen gas at STP will be produced when 1000g of aluminum is added to 4.00L of 1.40mol/L Sulfuric acid? @abb0t

Answer 1

@aaronq

Answer 2

so you got the balanced equation?

Answer 3

2Al + 6HCl ---> 2AlCl3 + 3H2

Answer 4

okay now, find the limiting reagent. we divide the moles of each of the reactants by their stoichiometric coefficient and see which one has less.

Answer 5

ok please wait let me do that step

Answer 6

okay

Answer 7

sorry it's not coming to mind :(
please give me a clue :(

Answer 8

okay, so for the aluminum, you wanna find the moles from the mass.

\(\sf moles=\dfrac{mass}{Molar~mass}\)

Answer 9

yah but we is the mass?

Answer 10

For the sulfuric acid, you need the moles from the molarity and the volume

\(\sf Molarity=\dfrac{moles}{L}\)

Answer 11

we don't have the mass given in this question

Answer 12

1000g of aluminum

Answer 13

ok thanks...

Answer 14

so would it be 1000g/36.46 = 27.42mol

Answer 15

of cl2

Answer 16

now find the moles of sulfuric acid

Answer 17

that should've been aluminium

Answer 18

oh sorry...

Answer 19

yah aluminum

Answer 20

yah but i don't have the mount of Cl2

Answer 21

in grams

Answer 22

It's not even asking for \(Cl_2\)

Answer 23

it's not in the question

Answer 24

sorry its 5.6 mol

Answer 25

sorry i mean sulfuric acid :(

Answer 26

i'm having a really bad day :'(

Answer 27

okay, divide each by their coefficients

Answer 28

aw sorry to hear that
