The chemical formula for it is PbI2, but to have an equation there must be another reactant or specified phase.
PbI2
The balanced equation is 2 KI + Pb(NO3)2 -> 2 KNO3 + PbI2.
Formula: CsI
A reaction doesn't occur.
Cl2 + 2NaI ---> 2NaCl + I2
Cl2 + 2KI --> 2KCl + I2
The balanced equation is 2 KI + Pb(NO3)2 -> 2 KNO3 + PbI2.
Pb2+ + I- --> PbI2(s)potassium and acetate ions are left out of the equation, because they don't react (stay unchanged in solution)
Pb(NO3)2(aq) + 2KI)aq) = 2KNO3(aq)+ PbI2(s) PbI2 is a yellow coloured solid and will precipitate out of the solution.
Formula: CsI
Pb(NO3)2(aq) + 2NaI(aq) → PbI2(s) + 2NaNO3(aq) Aqueous lead II nitrate reacts with aqueous sodium iodide to form solid lead II iodide precipitate and aqueous sodium nitrate.
Balanced:2 HI ----> H2 + I2
That would be AgI!
No reaction.
2i + 3cl2 --> 2icl3
A reaction doesn't occur.
No reaction because the anion is common in both compounds.
potassium
