Alright Ignatius — let's do this. I) Explain why a plastic container is used instead of a metallic one. A plastic container is used because plastic is a poor conductor of heat (an insulator). This minimizes heat loss to the surroundings, ensuring that the measured heat change for the reaction is as accurate as possible. A metallic container, being a good conductor of heat, would allow significant heat loss, leading to inaccurate results. II) Write an ionic equation for the reaction between zinc powder and copper(II) sulfate solution. Step 1: Write the full chemical equation. Zinc reacts with copper(II) sulfate to form zinc sulfate and copper. Zn(s) + CuSO_4(aq) ZnSO_4(aq) + Cu(s) Step 2: Write the complete ionic equation. Separate the aqueous ionic compounds into their respective ions. Zn(s) + Cu^2+(aq) + SO_4^2-(aq) Zn^2+(aq) + SO_4^2-(aq) + Cu(s) Step 3: Identify and cancel spectator ions. The sulfate ion (SO_4^2-) appears on both sides of the equation, so it is a spectator ion. Zn(s) + Cu^2+(aq) + SO_4^2-(aq) Zn^2+(aq) + SO_4^2-(aq) + Cu(s) Step 4: Write the net ionic equation. The remaining species form the net ionic equation. Zn(s) + Cu^2+(aq) Zn^2+(aq) + Cu(s) Last free one today — make it count tomorrow, or type /upgrade for unlimited.
