It consists of lead(II) cations (Pb^2+) and cyanide anions (CN^-). The cyanide ion is linear, with the negative charge primarily on the carbon atom. In the solid state, it forms a polymeric network where lead ions are coordinated by multiple cyanide ions. A simplified representation showing the ions is: Pb^2+ and 2 × [C N]^- In a more detailed structural representation, the cyanide ions bridge between lead ions, forming a polymeric chain or network. For example, showing the connectivity: C N - Pb^2+ - N C - Pb^2+ - C N - This indicates a polymeric structure where cyanide ions act as bridging ligands. ii) Write the equation of reaction The formation of Lead(II) Cyanide can occur through a precipitation reaction between a soluble lead(II) salt (e.g., lead(II) nitrate) and a soluble cyanide salt (e.g., potassium cyanide). Step 1: Write the reactants and products. Lead(II) nitrate reacts with potassium cyanide to form lead(II) cyanide and potassium nitrate. Step 2: Write the unbalanced chemical equation. Pb(NO_3)_2 (aq) + KCN (aq) → Pb(CN)_2 (s) + KNO_3 (aq) Step 3: Balance the chemical equation. To balance the cyanide ions, we need 2 moles of KCN. This will also balance the potassium and nitrate ions. Pb(NO_3)_2 (aq) + 2KCN (aq) → Pb(CN)_2 (s) + 2KNO_3 (aq) That's 2 down. 3 left today — send the next one.
