Question

Given the following unbalanced chemical equation, how many grams of aluminum chloride are produced when 3.00 moles of aluminum reacts with 5.30 moles of chlorine gas?
___Al + ___ Cl2 arrow ___AlCl3

Answer 1

471 grams


399 grams


151 grams


177 grams

Answer 2

can u tell molecular weight of Al Cl2 and AlCl3

Answer 3

AI- 26.98153868 CI2- 70.9064 AICI3- 133.3411

Answer 4

anc can you balance the reaction and write it

Answer 5

I do not think so

Answer 6

mean u dont know

Answer 7

yes, I do not know lol

Answer 8

:)

Answer 9

help! lol :)

Answer 10

2Al + 3Cl2 = 2AlCl3 is a balanced equation

Answer 11

wow I was sooooooo off.... how do I figure out grams now?

Answer 12

for 2 moles of Al how many moles of Cl2 is required can you tell

Answer 13

3?

Answer 14

yaaa right

Answer 15

yay! now what?

Answer 16

now you have to check which one is limiting reagent

Answer 17

oh gosh... I would say CI2

Answer 18

mean Cl2 is in excess than the Al right
bcoz 2 mole of Al needs 3moles of Cl2 from balanced equation
but in ur question they have mentioned for 3 moles of Al reacts with 5.30 moles
since Cl2 is huge amount hence it is not limiting reagent
limiting reagent is Al

Answer 19

2mole s of Al give rise too 2 moles of alCl3
3 moles of Al give rise too =3*2 /2 =3 moles of AlCl3

u have to convert moles into grams
grams = moles * molecular weight of AlCl3
= 3 * 133.34
= 400 gram

Answer 20

can u guess the answer now

Answer 21

the only one that comes close is 399...

Answer 22

yaaa that is the answer LOL:)

Answer 23

OH!! AWESOME!
