oxyen and water

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 happens during oxidation reactions?
hat happens in an oxidation reaction? to9u
What is the relationship between oxidation and reduction?
Oxidation and Reduction reactions occur when electrons are transferred. The molecule that is oxidized loses an electron and the molecule that is reduced gains the electron that was lost by the oxidized molecule. Therefore, oxidation and reduction have to occur together.
What happens during oxidation?
in oxidation reaction addition of electron occurs.
What is an example of a reduction reaction?
An example of elimination reaction is seen in the reaction of isobutylbromide with potassium ethoxide in ethanol. Isobutylene, ethanol and potassium bromide is the resulting reaction.
What happens when electrons are gained or lost?
Gain or electron means reduction energy is not gained but given off during this and also when oxidation takes place the same thing thing happens' energy is released when a redox reaction takes place(ie both oxidation & reduction)
What happens during paper is burning?
This is an oxidation reaction; carbon dioxide and water are released.
Are carbon atoms changed during burning?
Burning is a combustion reaction, which is a type of oxidation-reduction reaction. During combustion, carbon is oxidized. This means that it oxidation state becomes more positive, since it loses electrons during the reaction (it is bonded to the more electronegative oxygen after the reaction, whereas it was bonded to less electronegative hydrogen before the reaction).
During ionic bonding what is the reduction and oxidization?
Simply, reduction is the gaining of electrons and oxidation is the donating of electrons.
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.)
What happens when an atom is not oxidized or reduced during a reaction?
then its oxidation state remains constant butattached atoms become changed, such reactions are double displacement reactions.
What is cathodic reaction?
Taken from Introduction To Corrosion Science by E. McCafferty Two notable things occur during a cathodic reaction. 1.) A given species undergoes reduction (there is a decrease in its oxidation number) 2.) A gain of electrons at the cathodic site (electrons are consumed by the reaction) An example of a cathodic reaction is: 2H+(aq) + 2e- ==> H2(g) This reaction however is just a half-cell reaction, which means it is usually coupled (happens along with) an anodic reaction.
