Answer 1

1) The balanced equation for reaction between aq. strontium iodide and aq. plumbous nitrate is

SrI₂ (aq) + Pb(NO₃)₂ (aq) ---------->PbI₂ (s) + Sr(NO₃)₂ (aq)

Here, solid PbI₂ fomred.

Hence, it is a precipitation reaction.

2) The balanced equation for reaction between aq. copper (II) nitrate and and aq. nickel (II) sulfate is

Cu(NO₃)₂ (aq) + NiSO₄ (aq) ----------> CuSO₄ (s) + Ni(NO₃)₂ (aq)

   Here, solid CuSO₄ fomred.

Hence, it is a precipitation reaction.

3) The reaction between gaseous sulfur dioxide and gaseous oxygen and liquid water produce H₂SO₄ (acid rain)

SO₂ (g) + 2O₂ (g)+ 2H₂O (l) --------> 2H₂SO₄ (aq)

It is a combination reaction. It is also called synthesis reaction.

4) In electrochemical series , gold is placed below Hydrogen.

Hence, gold cannot displace hydrogen from perchloric acid ( HClO4).

Therefore, no reaction.

Au + HClO₄ ----------> No reaction

5) When Solid sodium is added to liquid water, sodium hydroxide will be formed and hydrogen gas will be evolved.

2Na (s) + 2H₂O (l) ---------> 2 NaOH (aq)+ H₂ (g)

H₂ is displaced. Hence, It is a single displacement reaction.

6)

4Fe(s) + 3O₂ (g) ------------> 2Fe₂O₃(s)

It is a combination reaction. It is also called synthesis reaction.
