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 oxidation number of oxygen and and how?
The oxidation number of an element depend on another element it react with to form a compound e.g manganese(iv)oxide mno4 the oxidation number of oxygen there is four while the oxidation number of manganse is 7 in most radox reaction the oxidation number of oxygen is usually 4 when writing the full equation
Why is the conversion of ethanol to ethnoic acid an oxidation reaction?
* To be an oxidation reaction electrons have to be lost. * Any reaction that results in electrons being lost can be described as an oxidation reaction.
When a species in a chemical reaction loses electrons The oxidation number increases?
Yes.
Which element increases its oxidation number in the following reaction 2na plus 2h2o---2naoh plus h2?
Sodium - it goes from oxidation number 0 to +1
Why numbers in balanced equation are consistent with changes in oxidation numbers?

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
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.
Which element increases its oxidation number in this reaction 3koh h3po4 k3po4 3h2o?
None. All oxidation states stay the same in this reaction.
In a combustion reaction the always changes oxidation number making this aN reaction?
oxygen, redox
Is the reaction agno3 plus fecl3 equals agcl plus fe no3 3 redox?
No, it is not a redox reaction. None of the oxidation numbers changes during the reaction. You have to determine the oxidation number for each element and see if it changes from reactant side to product side. If the oxidation number doesn't change, it is not a redox reaction.
What does H2 do to N2 to make NH3?
It reacts with it. The reaction is a redx reaction. Nitrogen is reduced (its oxidation number goes from 0 to -3) and hydrogen is oxidised (its oxidation number goes from 0 to +1)
What occurs at the cathode of a galvanic cell?
An oxidation half-reaction
Is N2O4 ---- 2NO2 a redox reaction?
No. The oxidation numbers of nitrogen and oxygen do not change.
Why do you need to know the oxidation number of the elements?
because if you know the oxidation numbers of all the reactants and products in a given reaction, you can determine which, if any, of the reactants were oxidized and which were reduced. oxidized is when the oxidation number increases, reduced is when the oxidation number decreases.
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.
