Question

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)

Answer 1

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)
