(circle)

Explanation / Answer

4. Observation of potasium chloride and sodium nitrate :Both are soluble and all possible products are soluble too. So, you just get 4 ions in solution without any precipitate or gas Molecular equation of potasium chloride and sodium nitrate:The formula for potassium chloride is wrong. It should be KCl. The equation above is a double-displacement reaction. The molecular equation is KCl + NaNO3 --> KNO3 + NaCl Remember that both of the reactants are aqueous, meaning, they are dissolved in water. When an ionic substance dissolves in water, it separates into its ions. We account for this by separating each substance in the equation to ions. The complete ionic equation is K+ + Cl- + Na+ + NO3- --> K+ + NO3- + Na+ + Cl- As for the net ionic equation, I'd say we can't write one because all of the ions here are spectator ions. They all appear on both sides so they all cancel out. This shows that both products are soluble in water. IONIC EQUATION The formula for potassium chloride is wrong. It should be KCl.
