Select the correct answer:
1.
Identify the balanced chemical equation for the reaction between potassium iodide and lead nitrate.
\(Pb(NO_3)_2 + 2KI → 2KNO_2 + PbI_2\)
\(Pb(NO_3)_2 + KI → KNO_3 + PbI_2\)
\(Pb(NO_3)_2 + 2KI → 2KNO_3 + PbI_2\)
\(Pb(NO_3)_2 + 2KI → 2K_2NO_3 + PbI_2\)
2.
Which of the following pairs can show a displacement reaction?
\(Zn + CuSO_4\)
\(Ag + CuSO_4\)
\(Cu + ZnSO_4\)
\(Cu + FeSO_4\)
