Static Friction, Sliding Friction, Rolling Friction, and finally Fluid Friction.
Answer :
is the oxidizing agent and Fe is the reducing agent.
Explanation :
Reducing agent : It is defined as the agent which helps the other substance to reduce and itself gets oxidized. Thus, it will undergo oxidation reaction.
Oxidizing agent : It is defined as the agent which helps the other substance to oxidize and itself gets reduced. Thus, it will undergo reduction reaction.
The balanced redox reaction is :
![4Fe+3O_2\rightarrow 2Fe_2O_3](https://tex.z-dn.net/?f=4Fe%2B3O_2%5Crightarrow%202Fe_2O_3)
The half oxidation-reduction reactions are:
Oxidation reaction : ![Fe\rightarrow Fe^{3+}+3e^-](https://tex.z-dn.net/?f=Fe%5Crightarrow%20Fe%5E%7B3%2B%7D%2B3e%5E-)
Reduction reaction : ![O_2+4e^-\rightarrow 2O^{2-}](https://tex.z-dn.net/?f=O_2%2B4e%5E-%5Crightarrow%202O%5E%7B2-%7D)
In order to balance the electrons, we multiply the oxidation reaction by 4 and reduction reaction by 3 then added both equation, we get the balanced redox reaction.
Oxidation reaction : ![4Fe\rightarrow 4Fe^{3+}+12e^-](https://tex.z-dn.net/?f=4Fe%5Crightarrow%204Fe%5E%7B3%2B%7D%2B12e%5E-)
Reduction reaction : ![3O_2+12e^-\rightarrow 6O^{2-}](https://tex.z-dn.net/?f=3O_2%2B12e%5E-%5Crightarrow%206O%5E%7B2-%7D)
![4Fe+3O_2\rightarrow 2Fe_2O_3](https://tex.z-dn.net/?f=4Fe%2B3O_2%5Crightarrow%202Fe_2O_3)
In this reaction,
is the reducing agent that loses an electron to another chemical species in a redox chemical reaction and itself gets oxidized and
is the oxidizing agent that gain an electron to another chemical species in a redox chemical reaction and itself gets reduced.
Thus,
is the oxidizing agent and Fe is the reducing agent.
Answer: you can’t
Explanation: i’m dumb too
Answer:
sediment from melting glaciers being deposited in lakes
Explanation:
I took the test
Crystallization
This is because insects that usually get stuck in sap tend to harden or crystallize, so they cannot get out. That is why it is a crystallization.
