Yes, Fe(s)+CuSO4→FeSO4(aq)+Cu(s) is a redox reaction. The reducing agent is Fe(s), while the oxidizing agent is CuSO4.
<h3>Oxidation-reduction reaction (redox)</h3>
Oxidation-reduction reaction is the type of reaction in which electrons are transferred from one element to another. A compound or an element either gains are looses an electron in redox reactions.
Fe(s)+CuSO4→FeSO4(aq)+Cu(s)
From the equation above, Fe(s) is the reducing agent because it gives away 2 electrons and undergoes oxidation reaction.
From the equation above, CuSO4 is an oxidizing agent because it gives oxygen to Fe(s) and undergoes a reduction reaction.
Therefore, the reducing agent is Fe(s), while the oxidizing agent is CuSO4.

Answer:
mercury or Hg
Explanation:
i looked at the periodic table haha
hope this helps and is right <3
Answer:
33300J
Explanation:
Given parameters:
Mass of ice = 100g
Unknown:
Amount of energy = ?
Solution:
This is a phase change process from solid to liquid. In this case, the latent heat of melting of ice is 3.33 x 10⁵ J/kg.
So;
H = mL
m is the mass
L is the latent heat of melting ice
Now, insert the parameters and solve;
H = mL
mass from gram to kilogram;
100g gives 0.1kg
H = 0.1 x 3.33 x 10⁵ = 33300J
Imidazole's cyclic structure is aromatic and the lone pair present at the N₁ atom available for donation. hence, according to question N₁ is the most basic atom in the structure.
<h3>
What is resonating structure?</h3>
- Two π bonds (between C₂-C₃ and N₁-C₅), as well as one lone pair on N₄, can interact with one another to generate a delocalized π system in the cyclic structure.
- This delocalization is intriguing since it has the same number of delocalized electrons as benzene—six.
- As a result, imidazole, like benzene, has a closed, delocalized ring with six π electrons. So, like benzene, it is regarded as an aromatic chemical with resonance stability.
- N₄ is neutral since it cannot be donated because it needs to use its lone pair to be aromatic.
- On the other hand, N₁ already forms a π connection, which helps the system become delocalized.
- N₁ is sp² hybridized and has a trigonal planar basic form. Its lone pair cannot communicate with the delocalized π system since it is pointed away from the cyclic structure.
