Is N2O4 ---- 2NO2 a redox reaction?
No. The oxidation numbers of nitrogen and oxygen do not change.
Which balanced equation represents an oxidation-reduction reaction?
Equations that separate the oxidation from the reduction parts of the reaction
Do all oxidation-reduction reactions have in common?
They both occur simultaneously in a redox reaction.
What is copper oxide reduced to when it reacts with carbon?
2CuO + C CO2(g) + 2CuCuO is reduced because the oxidation number of copper decreases from +2 (in CuO) to 0 (in Cu).C is oxidised because the oxidation number of carbon increases from 0 (in C) to +4 (in CO2).So this can be considered a redox reaction as both reduction and oxidation occurs at the same time. Since CuO is reduced, it acts as the oxidising agent. Since C is oxidised, it acts as the reducing agent.
What is the oxidation half reaction of Cl2 2Cu to 2CuCl?
Cl2 + 2Cu --> 2CuCl Oxidation reaction is Cu --> Cu+ + 1e Reduction reaction is Cl + 1e --> Cl- Redox reaction is Cu + Cl --> Cu+ + Cl-
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.
Is N2O4 ---- 2NO2 a redox reaction?
No. The oxidation numbers of nitrogen and oxygen do not change.
What elements do redox reaction get?
oxidation
What is short for oxidation reduction?
"Redox"
What is short for oxidation-reduction?
redox
What is the word equation for copper sulphate and zinc?
This is called a reduction / oxidation reaction:Reduction of Cu2+ to Cu , done by electron donation from Zn which is then oxidized to Zn2+.Sulfate ions (SO42-) do not take part in this, they're called: tribuned ions.
Why numbers in balanced equation are consistent with changes in oxidation numbers?
This is because when we balance a redox reaction, the stoichiometric coefficients are such that the total positive Oxidation number in the reaction and the Total negative Oxidation number corresponds to the net charge of the reaction.
What is the chemical name of the product when copper reacts with gas in the air?
Copper reacts with the oxygen in the air in a process called oxidation. This occurs in several steps as seen in Kuba Jasinski’s answer. The reactions occur as the copper atoms give up some electrons (oxidation) to the oxygens (reduction) to create ionic compounds. This is a classic example of what is called a redox (reduction-oxidation) reaction.
How can you tell for sure that a redox reaction has happened?
if oxidation states change, it is a redox reaction
What is an oxidation reduction or redox reaction?
ik
What is the change in oxidation number for the iodide ion in redox titration?
Reductant Iodide (I-) can be oxidised to other (more postive) oxidation numders by loosing electrons to the oxidant. Depending on the oxidant's strength this can change to the following numbers: 0 (zero) in I2 , and +1, +2, +3, +4 (in hypoiodite IO-, iodite IO2-, iodate IO3-, periodate IO4- respectively)
Is oxidation endothermic?
An oxidation reaction is also known as a redox reaction. Not all redox reactions give off heat. Some redox reactions give off heat and some require heat from an outside source for the reaction to be completed.
