Explain why it was important to clean each piece of metal you used with sandpaper prior to doing the experiment. (2) What specific problem might you have encountered had you cleaned the metal surfaces witha soft tissue instead? On the basis of your results from this experiment, what observation(s) did you make that woul allow you to determine the place H2 would take in your relative activity series?

Answer: Metal has a oxide layer when in air. Before an experiment cleaning it with sand paper will remove the leyer of oxide and ensure truer results. Cleaning with tissue paper will not result in removing the layer of oxide.

Shows how active H2 can be.

Following are the responses to the given question:

For question 1:

Sandpaper must be used to polish the metallic surface utilized for the experimentation.
Metals oxidize in the environment, forming an oxide coating on the surface thus rendering them unreactive.
As a consequence, sand is required to remove this before continuing with the reaction.

For question 2:

Then using soft tissue to cleanse a metal's surfaces, the oxides layer on top remains intact.
The metal does not fully react underneath the response circumstances.
As a consequence, the experimental data were untrustworthy and incorrect.

For question 3:

Unless the metal inside the experiment can generate H2, it's much less reactive than Hydrogen.
In the relative series, the metal gets put below the hydrogen.
When creating the hydrogen, suggesting that metals are acting as a strong reduction agent.
Most metals in the range above hydrogen act as oxidizing agents, while most metals below hydrogen act as reductants.
