A: 2H₂ + O₂ → 2H₂O

    H: 4            H:4
    O: 2           O: 2

The equation is balanced.

B. 2S + 3O₂ → 2SO₃

     S: 2             S: 2
     O: 6            O: 6

The equation is balanced.

C. Li + Cl₂ → LiCl

     Li: 1          Li: 1
    Cl: 2          Cl: 1

The equation is not balanced.

    2Li + Cl₂ → 2LiCl

    Li: 2            Li: 2
    Cl: 2           Cl: 2

D: 2K + 2H₂O → H₂ + 2KOH

    K: 2                 K: 2
    H: 4                 H: 4
    O: 2                 O: 2

The equation is balanced.

E: 2Fe + Cu(NO₃)₂ → 2Cu + Fe(NO₃)₂

    Fe: 2                       Fe: 1
    Cu: 1                      Cu: 2
      N: 2                        N: 2
      O: 6                        O: 6

The equation is not balanced.

2Fe + 2Cu(NO₃)₂ → 2Cu + 2Fe(NO₃)₂

Fe: 2                        Fe: 2
Cu: 2                       Cu: 2
  N: 4                         N: 4
  O: 12                       O: 12

The following equations that are balanced are A, B, and D.

If the formula for a compound is represented by X3Y2 and the charge on the Y ion is -3, what is the charge in the X ion?
artcher [175]
I cannot fully remember but the charge of a compound always has to be the same.  However, I believe that the sign of the Y2 means that it is positive 2. 

so in my opinion it is in between b and c. use your best judgment.
