Redox/Oxidation lab with Metals and Halogens
So basically we were testing different reactions and observing changes. I want to know if my data has the "right" reactions, as the supplies used in the chemistry lab were contaminated a LOT by people who used pipettes wrong. So now I'm confused.
Part A:
Each tube had 1 mL of 6M HCl. Different pieces of metal were added in each tube. Here are my results:
| Tube | Metal | Reaction |
| 1 | Mg | bubbling |
| 2 | Fe | none |
| 3 | Cu | heat/steam |
| 4 | Zn | bubbly |
| 5 | Sn | steam (?) |
Part B:
Each tube had 1 mL of a designated solution and then various metals added to them (separately)
| Solution | Reaction | ||||
| Zinc | Copper | Iron | Magnesium | Tin | |
| AgNO3 | Foggy | black | none | dissolved | dissolved |
| Cu(SO4) | None | none | red | dissolved | none |
| FeSO4 | orange? | none | none | fizzy(?) | none |
| SnCl2 | foggy? | none | none | dissolved | none |
| Zn(NO3)2 | None | none | none | none | none |
Part C:
1 mL of cyclohexane and a few mL of the element-saturated water were added to different tubes. Observing color on top and on bottom (they separated)
| Br2 | Cl2 | I2 | |
| cyclohexane layer (top) | violet | clear | violet |
| water layer (bottom) | red | clear | red |
Then comparing that with testing them with different stuff...
Part D:
1 mL of NaBr, NaI or NaCl was added to various tubes of 1 mL of either bromine, chlorine or iodine saturated water. Colors were observed as top color/bottom color:
| NaBr | NaCl | NaI | |
| Br2 | N/A | violet/red | violet/red |
| Cl2 | clear/clear | N/A | pink/yellow |
| I2 | violet/red/orange | violet/orange | N/A |
Then we're supposed to write net ionic equations for every reaction in the experiment. no idea how to do that so an example would be nice. Then we're supposed to devise an activity series of the metals (plus hydrogen) listed in order of decreasing activity.
For the halogens we're supposed to do an activity series in order of decreasing strength as oxidizing agents.
I know it's a lot to ask, but I just basically want someone who knows chemistry really well to tell me the proper reactions for this, I'm having trouble finding it online but i'll continue to search.
Thanks

1. The activation energy of a certain reaction is 41.5kJ/mol . At 20 ?C , the rate constant is 0.0110s?1. At what temperature in degrees Celsius would this reaction go twice as fast?
2. Given that the initial rate constant is 0.0110s?1 at an initial temperature of 20?C , what would the rate constant be at a temperature of 180?C for the same reaction described in Part 1?
