3. afua mixes a solution of potassium iodide with a solution of lead nitrate.birth of the solutions are clear and colourless.the resulting mixture is cloudy and yellow.the yellow precipitate is lead iodide,one of the products on this reaction.what is the name of the other products
Jawaban:
Potassium nitrate KNO[tex]_{3}[/tex]
Penjelasan:
2KI + Pb(NO[tex]_{3}[/tex])[tex]_{2}[/tex] ------> 2KNO[tex]_{3}[/tex] + PbI[tex]_{2}[/tex]

4. Which of the following chemicals is a nonelectrolyte?a. molten naphthalenab. sodium hydroxide solutionc. aqueous sulfuric acid solutiond. aqueous ethanoic acid solutione. aqueous potassium iodide solution
The First thing that you must knew about Electrolyte Solution, Have the Criteria:
- The Solution that Perfect Ionized
- Strong Acid or alkali (have strong electrolyte) and weak Acid or alkali (have Weak Elektrolytes)
- Salt Solution (NaCl, KCl, and any others)
I thing Molten Napthalena Is the best Answer, Napthalena as an Organic coumpund has a Stabilized structur, so dificult to ionized.
I Hope that answer your question...

6. berapa jumlah mol atom potassium yang terdapat dalam 3.04 g potassium? Diketahui massa atom relative potassium adalah 49.1 g / mol.
mol = massa : Mr/Ar
mol = 3.04 g : 49.1 g/mol
mol = 0.0619 mol

9. Allah SWT created the earth with abundance of minerals. A sample mineral contained only chloride, iodide and nitrate anions. A titration was carried out to determine the chloride and iodide content. Standardized silver nitrate was used as titrant, and a silver wire immersed in the solution was used to monitor the solution’s electrochemical potential as the precipitates formed. The concentration of the standardized silver nitrate solution was 0,1 M. The burette initial reading was 1.35 mL, and the volumes at the two end points were 12.75 ml and 40.95 mL. Given that the original sample was 0.5 g, what is the percentage difference between iodide and chloride in the sample? (Ksp AgCl = 1,78 x 10-10, AgI = 9,8x10-17), (Molar mass, g.mol-1 for I=126,9, Cl=35,55) (Note: please write the answer IN NUMBER, WITHOUT writing the unit)
