* Lead is not involved: The reactants you've listed are sodium (Na) and nitrate (NO₃⁻). There's no lead (Pb) present.
* Nitrate is a polyatomic ion: Nitrate (NO₃⁻) is a negatively charged ion and cannot exist on its own. It needs to be paired with a positively charged ion to form a neutral compound.
* Sodium nitrate is a stable compound: Sodium and nitrate will react to form sodium nitrate (NaNO₃), a stable compound.
To make lead chloride (PbCl₂), you would need to react a lead compound with a chloride compound. For example:
Reaction:
Lead(II) nitrate (Pb(NO₃)₂) + Sodium chloride (NaCl) → Lead chloride (PbCl₂) + Sodium nitrate (NaNO₃)
Balanced Equation:
Pb(NO₃)₂(aq) + 2NaCl(aq) → PbCl₂(s) + 2NaNO₃(aq)
Explanation:
* The reaction produces a precipitate of lead chloride (PbCl₂) because it is insoluble in water.
* The coefficients in front of each compound ensure that the number of atoms of each element is equal on both sides of the equation.
