Examples of non-redox reaction?
Any reaction that doesn't have at least one atom that increases in oxidation number during the reaction and at least one atom that decreases in oxidation number during the reaction is not a redox reaction. The atom that decreases and the atom that increases can be atoms of the same element. Examples: 2H2 + O2 --> 2H2O ( Atoms of elements have an oxidation number of 0, so that the hydrogen atoms change from 0 to +1, which is oxidation, while the oxygen atoms change from 0 to -2, which is reduction. So the reaction is a redox reaction.) An example of a reaction in which atoms of the same element undergo both oxidation and reduction is: 2 MnO4- (aq) + 5 Mn (s) + 16 H+ (aq) -> 7 Mn+2 (aq) + 4 H2O (l). (In this reaction, 2 manganese atoms change from +7 to +2, which is reduction, and 5 manganese atoms change from 0 to +2, which is oxidation. ) An example of a non-redox reaction is Pb(NO3)2 (aq) + Na2SO4 (aq) ---> 2 NaNO3 (aq) + PbSO (s). (No atom changes its oxidation state in this reaction.)
Is oxidation a physical change?
Oxidation and reduction are chemical changes.
What is meant by oxidation number of an atom?
The oxidation number of an atom describes the number of electrons that an element has partially/entirely accepted/donated. A neutral atom has oxidation number of 0. When forming an ion, the overall oxidation number is equivalent to its charge.
How does the oxidation number indicate if an electron will be lost or gained?
If an atom loses electron, then it will have a positive oxidation number. If an atom gains electron, then it will have a negative oxidation number.
Oxidation in terms of oxidation number?
Oxidation number increases when the atom is oxidised, and decreases when it is reduced
When an atom undergoes oxidation what happens to the number of neutrons?
Oxidation is a chemial reaction; the atom and the number of neutrons remains unchanged.
Is oxidation a reaction between iron water and oxygen?
No. Oxidation is the loss of electrons by an atom, or equivalently an increase in the oxidation number of that atom. Rust formation is one example of oxidation.
What is it called when the number of protons in an atom change?
The only way to change the number of protons in an atom is with a nuclear reaction.
What happens during a reduction/oxidation reaction?
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron

What kind reactions are red ox reactions?
Oxidation states have changed.

Oxidation in terms of oxidation number?
Oxidation number increases when the atom is oxidised, and decreases when it is reduced
What is meant by Auto-redox reaction?
Auto-redox reaction in which the oxidation number of an atom within a molecule changes as the compound changes on each side of the equation.
What is the used to determine the number of each atom in an ionic formula?
Oxidation state is what determines the number of each atom. This is in the ionic formula.
