CH3-CH=CH2+Br2--->CH3-CH(Br)-CH2-Br
Answer:
Fe
Explanation:
The cell potential is:
ΔE°cell = E°red(red) - E°red(oxid)
Where, E°red(red) is the reduction potential of the substance that is reducing, and E°red(oxid) is the reduction potential of the substance that is oxidizing. For the reaction be spontaneous and happen, ΔE°cell > 0.
The reduction takes place in the cathode, which is the negative pole, and the oxidation in the anode, which is the positive pole. So, the electrons flow from the positive pole to the negative pole (anode to cathode).
Then, if the voltmeter measured a negative potential, it means that is was attached incorrectly. So, the anode is Fe.
There was a change in its color from white to red which can only be changed by a chemical reaction
the answer should be salad dressing
Just do it one at a time. How is heart rate affected by exersice? Well, think about it; When you run, your heart rate goes up. When you rest, it goes down.
Take you time, think carefully and you'll get it.
