Answer: Copper is being oxidized and acts as a reducing agent. In contrast, silver is being reduced, functioning as the oxidizing agent.
Explanation:
An oxidation reaction involves the loss of electrons by an atom. Here, the oxidation state of the atom rises.
Conversely, a reduction reaction is characterized by an atom gaining electrons, resulting in a decrease in its oxidation state.
Oxidizing agents are those that facilitate the oxidation of another substance while themselves being reduced. These substances participate in reduction reactions.
Reducing agentsare defined as those that reduce other substances while undergoing oxidation themselves. They also take part in reduction reactions.
In the provided chemical reaction:
The associated half-reactions for the above process are:
Oxidation half reaction:
Reduction half reaction:
From the reactions outlined, copper is losing electrons. Consequently, it is oxidized and regarded as a reducing agent.
Silver is acquiring electrons, thus it is being reduced and viewed as an oxidizing agent.
Answer:
The salt identified is barium chloride.
Explanation:
The moles of barium sulfate produced are
per the reaction, 1 mole of barium sulfate arises from 1 mole of .
Therefore, 0.0480 moles result from:
of
.
The quantity of used amounts to 10.00 g
Moles of = \frac{10.00 g}{\text{Molar mass}}[/tex]
The molar mass of is 208.33 g/mol
The closest answer to our calculation is .
The correct identification is barium chloride, which has a molar mass of 208.2 g/mol.
Answer: The correct choice is (b).
Explanation:
We have the mass of Magnesium at 97.22 g, and the molar mass of Magnesium is 24.305 g/mol.
Therefore, the calculation for the number of moles is as follows.
Number of moles =
=
= 4 mol
Additionally, it is known that one mole contains atoms/mol. Thus, we calculate the total number of atoms in 4 moles as follows.
= atoms
or, = atoms
Hence, we conclude that in 97.22 grams of Magnesium, there are atoms.
