# balance pb(no3)2+nai\u003dpbi2+nano3

2. Count the atoms in the reactants and products. 3. Place coefficients in front of molecules to balance the numbers of atoms.Answer: Pb(NO3)2 2NaI rarr PbI2 2NaNO3. Pb(NO3)2 is a white powder at room temperature. It is soluble in water. Pb(NO3)2 2NaI PbI2 2NaNO3. Lead salts from sulphates solutions precipitates white sediment, soluble at heating in alkalis and solution of ammonium acetate: Pb(CH3COO)2 Na2SO4 PbSO4 2CH3COONa PbSO4Solution of sodium thiosulphate discolours iodine solution: 2Na2S2O3 I2 Na2S4O6 2NaI. Write a balanced net ionic equation for the reaction below: Pb(NO3)2 (aq) NaI (aq) 2NaI(aq) Pb(NO3)2 (aq) PbI2(s) 2NaNO3 (aq). If the weight of any one species used or produced is known, the others are readily calculated. How much Pb(NO3)2 is need to convert 1.0 grams of NaI to PbI2? Pb(NO3)2 is soluble because it contains NO3.14. No Precipitate Formation No Reaction. KI (aq) NaCl (aq) KCl (aq) NaI (aq) all ions still present, no reaction.c) Write the formulas of the products - balance charges.

K2CO3(aq) NiCl2(aq) KCl NiCO3. c. Pb(NO3)2 NaI. PbI2 (solid) NaNO3. 6. Balance the equation and give the type of reaction. a. CaCO3.
