Solid iron is mixed with a solution of copper (I) nitrate to form iron (III) nitrate solution and metal copper. (what is the equ
DedPeter [7]

Answer:

Fe + 3CuNO₃ → Fe(NO₃)₃ + 3Cu

Explanation:

  • Solid Iron = Fe
  • Copper (I) nitrate = CuNO₃ (Nitrate, NO₃⁻, always has a charge of -1).
  • Iron (III) nitrate = Fe(NO₃)₃ (That way the compound has an overall neutral charge)
  • Metal Copper = Cu

Writing the equation using symbols leaves us with:

  • Fe + CuNO₃ → Fe(NO₃)₃ + Cu

<em>It is not balanced yet</em>. Now we <u>balance the NO₃ species on the left side</u>:

  • Fe + 3CuNO₃ → Fe(NO₃)₃ + Cu

Finally we<u> balance the Cu species on the right side</u>:

  • Fe + 3CuNO₃ → Fe(NO₃)₃ + 3Cu
