Question

Al + CaCl2 -> Metal + Salt

Answer 1

Is it going to be: Ca + AlCl2 or No Reaction? This is a single displacement reaction.

Answer 2

it should be AlCl3, but essentially you're correct

Answer 3

oh, I believe it's AlCl3 'cause of the cross multiplication of charges right? Al +3 Cl-2? So, Al2Cl3 or just AlCl3?

Answer 4

I meant Cl -1

Answer 5

yes, cross the charges: Al+3 and Cl-1.

Answer 6

But you know how you have to read an activity series cahrt for Singel displacement... Calcium is more reactive than Aluminum

Answer 7

whether the reaction happens will depend on activities yes, but if it were to happen, the reaction would look like what you have above.

Answer 8

ohh.. By the way, do you know the oxidation number for Cl4?

Answer 9

Do you mean the chage of a cl4 molecule? that would be negitive 4

Answer 10

ohhh.. i see, thank you!

Answer 11

Any time keep those questions coming i will do my best to figure them out!

Answer 12

I have this other question: Na + SnCl4 -> Metal + Salt. I put:

1 Na + 1 SnCl4 -> Sn + NaCl4 but since chlorine has a -4 charge and sodium has +1, should it be Na4Cl4? This is also a single displacement reaction.

Answer 13

So you can rewrite this as

\[4Na^+ +SnCl_4 \rightarrow Sn + 4 NaCl\]

NaCl is table salt, I need to check on the charge of Sn

Answer 14

Ok Sn can be +2 or +4 so we will just assume its plus four, you could also identify that by putting a roman numaral 4 in the subscript of the Sn atom

Answer 15

ohh, alright. Thank you!!
