<u>Answer:</u> The half reactions are written below.
<u>Explanation:</u>
Oxidation reaction is defined as the reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

We are given a chemical cell which is Fe-Sn cell. The half reaction follows:
<u>Oxidation half reaction:</u> 
<u>Reduction half reaction:</u> 
The substance having highest positive
potential will always get reduced and will undergo reduction reaction. Here, zinc will always undergo reduction reaction will get reduced.
<u>Total cell reaction:</u> 
Hence, the half reactions are written above.
1. Increasing
2. Increasing
3. Decreasing
4. Increasing
5. Decreasing
Explanation:
To solve this problem, we simply use the periodic table of elements which groups elements based on their atomic numbers.
The atomic number of an element is the number of protons it contains. The protons are the positively charged particles within an atom.
- The vertical arrangement of elements on the periodic table is the group.
- The horizontal arrangement of elements is the period.
Now;
Noble gases belongs to group 18
Alkali earth metals belongs to group 2
Halogens belongs to group 17
Alkali metals belongs to group 1
Transition metals belongs to group 3-12
Answer:
you should consider waterproofing. depending on the climate in your area, you need to apply multiple layers of waterproofing in the roof for it to support vegetation. you should also confused the types of plants. the types of plants is important for the success of your roof. if you live in a dry area, you don't want to choose plants that can live in dry areas without drying out.
It'd be a physical change. This is because it's a change in the state of matter and not altering the chemical structure of water
