What is the difference between oxidation reaction and a decomposition reaction?
Oxidation reaction is a process in which the atom or ion is increasing its oxidation sate. This includes a loss of electrons. Seen in the product side of a overall equation. The species that are being oxidized are the reduction agents. Reduction reaction is a process in which the atom or ion is decreasing its oxidation state. This includes a gain of electrons. They are seen in the reactants side through the overall equation.The species that are being reduced are the oxidizing agents.
How does one recognize redox reaction?
if oxidation states change, it is a redox reaction
What is weak reducing agent?
A reducing agent also known as reducer or reductant is the element or compound in oxidation reduction reaction. The reaction donates an electron to other species.
What happens to the number of electrons in an element when it is oxidized?
The oxidation number increases. For example when sodium reacts with chlorine to form sodium chloride, it is oxidised to and its oxidation number increases from 0 to +1, Chlorine is reduced and its oxidation number decreases from 0 to -1.
What species is reduced in the reaction Fe plus AgNo3 plus Fe(No3)3 plus Ag?
Ag+
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 is disproportionation reaction?
A disproportionation reaction is one in which a species has been both oxidised and reduced (that is, the oxidation state of the related species found in the products has increased in one instance, and decreased in another, in relation to that of the species found in the reactants). The classic example of disproportionation is the reaction between chlorine gas and dilute sodium hydroxide, although there are many others: Cl2 + 2NaOH --> H2O + NaCl + NaClO The oxidation state of chlorine is 0 in the reactants, but has decreased to -1 in NaCl AND has increased to +1 in sodium chlorate, NaClO.
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 species is reduced in the reaction Fe plus AgNO3Fe(NO3)3 plus Ag?
Fe(s) + 3AgNO3 ---> Fe(NO3)3 + Ag(s) The oxidation # of Ag on the left is 1+ and on the right it is zero. It has gained electrons and has been reduced.
When a species in a chemical reaction loses electrons The oxidation number increases?
Yes.

What species is reduced in the reaction Fe plus AgNO3 Fe(NO3)3 plus Ag?
Fe + 3AgNO3 ==> Fe(NO3)3 plus 3Ag The oxidation number of Ag in AgNO3 (on the left side) is 1+ and in Ag (on the right side), it is zero. Thus, in this reaction, silver (Ag) has been reduced.
How can oxidation numbers help chemists?
Oxidation numbers allow us to follow which species is being oxidised and which is being reduced. That way, we know which reactions are occurring and what the result will be.
Which balanced equation represents an oxidation-reduction reaction?
Equations that separate the oxidation from the reduction parts of the reaction
Are all reactions that form compounds from elements a redox reaction?
Yes, because an element is in oxidation state ZERO. A reaction is redox only when there is a change in oxidation state of relevant species. So if a compound is formed from elements (as opposed to other compounds) there by definition has to be a change in oxidation state.
What species is reduced in the reaction Fe AgNO3 Fe NO3 3 Ag?
Ag+ (apex)
What is weak reducing agent?
A reducing agent also known as reducer or reductant is the element or compound in oxidation reduction reaction. The reaction donates an electron to other species.
