The following reaction occurs in a car’s catalytic converter.
2 answers:
Answer:The correct answer is ;
The oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds.
Explanation:
In an oxidation recation addition of oxygen atom takes place or loss of electrons takes place.
In an reduction reaction removal of oxygen atom takes place or gain of electrons takes place.
In the given reaction , the nitrogen atom is present in +2 oxidation state in NO molecule and present in 0 oxidation state in molecule. Hence, nitrogen is getting reduced that is reduction reaction. NO is oxidizing agent
In the given reaction , the carbon atom is present in +2 oxidation state in CO molecule and present in +4 oxidation state in molecule. Hence ,carbon is getting oxidized that is oxidation reaction. CO is a reducing agent.
<u>Answer: </u>The correct statement is the oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds.
<u>Explanation:</u>
Oxidizing agent is the agent which oxidizes the other substance and itself gets reduced. The reaction it undergoes is reduction reaction. It gains electrons and the oxidation state of the substance gets reduced.
Reducing agent is the agent which reduced the other substance and itself gets oxidized. The reaction it undergoes is oxidation reaction. It looses its electrons and the oxidation state of the substance is increased
For the given chemical equation:
<u>On reactant side:</u>
Oxidation state of Nitrogen = +2
Oxidation state of Carbon = +2
Oxidation state of Oxygen = -2
<u>On product side:</u>
Oxidation state of Nitrogen = 0
Oxidation state of Carbon = +4
Oxidation state of Oxygen = -2
The oxidation state of carbon is increasing from +2 to +4, it is loosing electrons and thus it is undergoing oxidation reaction and CO is considered as a reducing agent. And the oxidation state of Nitrogen in reducing from +2 to 0, it is gaining electrons and thus it is undergoing reduction reaction and is considered as an oxidizing agent.
Hence, the correct statement is the oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds.

Answer:
This question is incomplete without the table
Explanation:
The missing table is attached to this answer.
There are three subatomic particles found in an atom; protons, neutrons and electrons. The properties of the subatomic particles will be classified under the following subheadings (which are the empty columns/boxes in the attachment)
SYMBOL
The symbol of proton is "p⁺", the symbol of neutron is "n⁰" and the symbol of electron is "e⁻".
CHARGE
Looking at the symbol of the subatomic particles, one can guess the charge of each of the particles from the superscript.
Protons are positively charged, electrons are negatively charged while neutrons have no charge/electrically neutral.
The relative charge of proton is +1 while it's absolute charge is +1.60218 × 10⁻¹⁹
The charge of a proton was first determined by Ernest Rutherford using the gold-foil experiment
The relative charge of electron is -1 while it's absolute charge is -1.60218 × 10⁻¹⁹
The charge of an electron was first determined by R. Milikan using the oil-drop experiment
The relative charge and absolute charge of neutron is 0
The charge of a neutron was first determined by (or credited to) James Chadwick.
MASS
The relative mass (amu) of proton is 1.00727 while that of neutron is 1.00866. The relative mass (amu) of an electron is 0.00054858 while it's absolute mass (g) is 9.10939 × 10⁻²⁴.
The mass of an electron was first measured by J. J. Thomson.
The mass of a proton was first measured by (or credited to) Ernest Rutherford.
The mass of a neutron was first measured by James Chadwick.
LOCATION
The protons and neutrons <u>are located inside the nucleus</u> which is found in the centre of an atom while the electron(s)<u> is/are found outside the nucleus but within the atom</u>.
