Answer:
Element.
General Formulas and Concepts:
<u>Chemistry</u>
- Reading a Periodic Table
- Diatomic Elements
Explanation:
Diatomic Elements are elements that are bonded to themselves. Naturally, these elements are not found alone in nature.
Diatomic Elements:
Hydrogen
Nitrogen
Oxygen
Fluorine
Chlorine
Bromine
Iodine
Since Nitrogen is a diatomic element, we would find Nitrogen in nature as N₂.
For the reactants,
- The oxidation number of hydrogen = +1
- The oxidation number of oxygen = -2
- The oxidation number of arsenic = +5
- The oxidation number of carbon = +3
For the products,
- The oxidation number of hydrogen = +1
- The oxidation number of oxygen = -2
- The oxidation number of arsenic = +3
- The oxidation number of carbon = +4
Here, arsenic (+5 to +3) and carbon (+3 to +4) are the only oxidation numbers changing.
Note that an increase in oxidation number means electrons are lost. Thus oxidation is occurring, and a decrease in oxidation number means electrons are being gained, and thus reduction is occurring.
Also, the compound that contains the element being oxidized is the reducing agent, and the compound that contains the element being reduced is the oxidizing agent.
So, the answers are:
name of the element oxidized: Carbon
name of the element reduced: Arsenic
formula of the oxidizing agent: ![\text{H}_{3}\text{AsO}_{4}](https://tex.z-dn.net/?f=%5Ctext%7BH%7D_%7B3%7D%5Ctext%7BAsO%7D_%7B4%7D)
formula of the reducing agent: ![\text{H}_{2}\text{C}_{2}\text{O}_{4}](https://tex.z-dn.net/?f=%5Ctext%7BH%7D_%7B2%7D%5Ctext%7BC%7D_%7B2%7D%5Ctext%7BO%7D_%7B4%7D)

Answer: Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds.
