Complete the following single replacement reaction. if they don’t react, just write “nr” 1). fe(s) +cucl2(aq) 2). cu(s) + fecl2(aq) 3). k(s) + nibr2(aq) 4). ni(s) + kbr(aq) 5). zn(s) + ca(no3)2(aq) 6). ca(s) + zn(no3)2(aq)

We have to complete all the given reactions.

1. Fe(s) + CuCl₂ → Cu + FeCl₂

2. Cu(s) + FeCl₂(aq)  → NR (no reaction takes place)

3. K(s) + NiBr2(aq) → NR (no reaction takes place)

4. Ni(s) + KBr(aq) → K + NiBr₂

5. Zn(s) + Ca(NO₃)₂(aq) → NR (no reaction)

6. Ca(s) + Zn(NO₃)₂(aq) → Zn(s) + Ca(NO₃)₂(aq)

idk what the question is about
