Question

Which process represents a general method for the preparation of a metal from its
compounds? .
(A) neutralization (D) fusion
(B) reduction (E) sublimation
(C) oxidation

Answer 1

quit asking so many questions

Answer 2

Hint:
If call the metal, M, and the anion, X, then MX ==> M + X

Does this look like an acid base reaction to you. Not to me.
It might be reduction.
It might be oxidation.
It CAN]T be fusion (since they are coming apart, not being fused.)
It CAN'T be sublimation because there is no vapor there. So look at the oxidation states and figures if its B or C.

Answer 3

I left out this with the problem

Ni2+(aq) + 2e¨C ¡ú Ni(s) ¨C0.25 V
Sn4+(aq) + 2e¨C ¡ú Sn2+(aq) +0.15 V
Br2(l) + 2e¨C ¡ú 2Br¨C(aq) +1.07 V

so it says:
Which process represents a general method for the preparation of a metal from its
compounds? .
(A) neutralization (D) fusion
(B) reduction (E) sublimation
(C) oxidation
Then this
Ni2+(aq) + 2e¨C ¡ú Ni(s) ¨C0.25 V
Sn4+(aq) + 2e¨C ¡ú Sn2+(aq) +0.15 V
Br2(l) + 2e¨C ¡ú 2Br¨C(aq) +1.07 V

Sorry about that

Answer 4

My screen doesn't tell me much. I have gibberish between the 2e and the metal for each of them.

Answer 5

Ni2+(aq) + 2e¨C ¡ú Ni(s) ¨C0.25 V
Sn4+(aq) + 2e¨C ¡ú Sn2+(aq) +0.15 V
Br2(l) + 2e¨C ¡ú 2Br¨C(aq) +1.07 V

Answer 6

Still gibberish.
