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 oxidation number of sulphur in the equation of combustion of H2S?
The oxidation number of sulphur in H2S is 2.
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.)
Is The decomposition of calcium carbonate into calcium oxide and carbon dioxide is an example of an oxidation-reduction reaction?
yes it is. CaCO3(s) → CaO(s) + CO2(g) bahala ka na mag redox."Notice there are no changes in oxidation number for any of the elementsCa remains as +2C remains as +4Oxygen remains at -2Since there is no change in oxidation number, it CANNOT be an oxidation-reduction reaction."-En3a 2014 UE Cal
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
In a combustion reaction the always changes oxidation number making this aN reaction?
oxygen, redox
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.
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 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 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.
What is the oxidation number of sulphur in the equation of combustion of H2S?
The oxidation number of sulphur in H2S is 2.
Hich of these is a description of a chemical property?
Chemical properties are: electronegativity, chemical affinity, activation energy, flammability, oxidation number, solubility, heat of reaction, heat of combustion, etc.

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.
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)
