What is the balance equation when calcium reacts with zinc chloride?
When calcium reacts with zinc chloride, the balanced chemical equation is: [ \text{Ca} (s) + \text{ZnCl}_2 (aq) \rightarrow \text{CaCl}_2 (aq) + \text{Zn} (s) ] In this reaction, solid calcium displaces zinc from zinc chloride, producing calcium chloride in solution and solid zinc.
What happens when zinc sulphate is added to barium chloride?
When zinc sulfate (ZnSO₄) is added to barium chloride (BaCl₂), a double displacement reaction occurs, resulting in the formation of barium sulfate (BaSO₄) and zinc chloride (ZnCl₂). Barium sulfate is insoluble in water and precipitates out as a white solid. The overall reaction can be represented as: ZnSO₄ + BaCl₂ → BaSO₄ (precipitate) + ZnCl₂. This reaction is often used in laboratory settings to demonstrate precipitation reactions.
Why does the mass of zinc chloride produced level off even though more and more zinc is being used?
The mass of zinc chloride produced levels off because zinc chloride is formed from a stoichiometric reaction between zinc and chloride ions. Once all available chloride ions are consumed in the reaction, adding more zinc will not result in additional zinc chloride production. This saturation occurs because the reaction is limited by the quantity of the limiting reactant, which in this case is the chloride source. As a result, excess zinc does not contribute to further zinc chloride formation.
Why was ionic precipitation chosen for the reaction of zinc sulphate and barium chloride?
Ionic precipitation was chosen for the reaction of zinc sulfate and barium chloride because it involves the formation of insoluble solid precipitates (zinc chloride and barium sulfate) from the combination of aqueous solutions of the two salts. This allows for the easy separation of the formed solid from the remaining solution.
What do you get when aqueous solutions of sodium carbonate and zinc chloride are combined?
When aqueous solutions of sodium carbonate and zinc chloride are combined, a double displacement reaction occurs. This results in the formation of zinc carbonate, which is a white solid precipitate that settles out of the solution, and sodium chloride, which remains dissolved in the solution.

What kind of reaction is zinc and hydrochloric acid?
Solid Zinc reacting with Hydrochloric Acid is a single replacement Oxidation/Reduction reaction.
How can you get zinc chloride by adding zinc sulphate into sodium chloride?
The reaction is not possible.
Could you determine the density of zinc chloride using water as a solvent?
Yes, the density of zinc chloride can be determined by measuring the mass of a known volume of the solution (a mix of zinc chloride and water) and then calculating the density using the formula: Density = mass/volume.
What happens if you mix zinc with ZnCl2?
When zinc metal is mixed with ZnCl2 (zinc chloride), a redox reaction occurs. The zinc metal will react with the zinc ions in the zinc chloride solution to form zinc atoms, while the chloride ions will remain in solution. This reaction usually results in the formation of more zinc metal and zinc chloride.
What compound is formed with chlorine and zinc?
many, zinc oxide, zinc carbonate, zinc chloride...

What elements are in this chemical reaction Zn s HCl g ZnCl s H?
zinc (Zn), hydrogen (H) and chlorine (Cl) are the elements present.
Why would a grey deposit be formed when platinum chloride is mixed with zinc?
The grey deposit forms due to a displacement reaction between platinum chloride and zinc. The zinc displaces the platinum from the compound, depositing it as a grey solid. This reaction is a common method for extracting platinum from its compounds.
Is zinc chloride a solid?
Yes. PbCl2 is a white solid, but it has a relatively low melting point for a metallic salt - just 501 degrees C as opposed to 801 degrees C for common salt sodium chloride or 786 degrees C for potassium chloride, or 772 degrees C for calcium chloride.
