Is oxidation chemical or physical reaction?
Oxidation is the recombination of atoms of one molecule with oxygen. An example might be the rusting of iron: 2Fe(s) + 3O2(g) --> 2Fe2O3(s) Therefore, oxidation is chemical reaction.
Which element increases its oxidation number in the following reaction?
An element that increases its oxidation number in a reaction has been oxidized. This means it loses electrons or gains a more positive oxidation state. You can determine which element is oxidized by comparing the oxidation numbers of the element in the reactants and products of the reaction.
What happens to atoms in an oxidation-reduction reaction?
The oxidation state of one atom increases while another decreases.
Can the oxidation number of an element change?
Yes, the oxidation number of an element can change depending on the chemical reaction it is involved in. The oxidation number reflects the number of electrons that an atom has gained or lost, so as atoms gain or lose electrons during a reaction, their oxidation numbers can change accordingly.
Why is the conversion of ethanol to ethnoic acid an oxidation reaction?
The conversion of ethanol to ethanoic acid involves adding oxygen to ethanol, which increases the oxidation state of carbon from -2 in ethanol to +2 in ethanoic acid. This increase in oxidation state indicates that oxidation has occurred, making it an oxidation reaction.
What is gained in a chemical reaction?
Electrons are the ones gained or lost in a chemical reaction. Electrons are gained in oxidation and lost through the chemical reaction known as reduction.
Any chemical reaction that involves the loss of one or more electrons by an atom or ion is a?
It is an oxidation reaction.
What chemical reaction with other substances is called oxidation?
A reaction witrh oxygen is called oxidation. Generally oxidation involve lose of electrons.
Is oxidation chemical or physical reaction?

What is a reaction that removes one or more electrons from a substance such that the substance's valence or oxidation state increases?
Oxidation reaction removes electrons from a substance, leading to an increase in its oxidation state or valence. This process involves the loss of electrons by the substance, which is typically accompanied by a reduction reaction in which another substance gains those electrons.
What do they call any chemical reaction that removes electrons from an atom?
oxidation
What completely describes a redox reaction?
A redox reaction, or reduction-oxidation reaction, is a chemical process in which electrons are transferred between substances, resulting in a change in oxidation states. It involves two half-reactions: oxidation, where a substance loses electrons and increases its oxidation state, and reduction, where a substance gains electrons and decreases its oxidation state. These reactions are fundamental in energy transfer processes, such as in batteries and metabolic pathways. Overall, they are characterized by the conservation of mass and charge throughout the reaction.
Which type of reaction results in a loss of electrons?
A reaction that results in a loss of electrons is called an oxidation reaction. During oxidation, an atom, ion, or molecule loses electrons, which increases its oxidation state. This process is often coupled with a reduction reaction, where another species gains the electrons that have been lost. Together, these reactions are part of redox (reduction-oxidation) processes.
Which element increases its oxidation number in the following reaction?

Why does the oxidation reaction undergo reduction?
Chemical reactions that result in transference of electrons
