both reactions are redox reactions
Oxidation and reduction are chemical properties. Electrolysis is a chemical process, not a property.
because all the elements has oxygen in it.
Oxidation-reduction, as magnesium is oxidized in this reaction
Yes, burning magnesium is an oxidation-reduction reaction. When magnesium metal burns, it reacts with oxygen in the air to form magnesium oxide, with magnesium being oxidized and oxygen being reduced.
All 4 are considered oxidation-reduction reactions
One possible pair of substances that could be involved in an oxidation-reduction reaction to form ions is magnesium and oxygen. In this reaction, magnesium would undergo oxidation to form Mg2+ ions, while oxygen would undergo reduction to form O2- ions.
when it reacts with leadoxide it become magnesuim oxide. this is because they lead and magnesuim have undergone a REDOx (reduction and Oxidation). the lead has been reduced and they magnesium has be oxidised!!!!!
In chemistry, reduction is considered the gaining of electrons. Oxidation is the lose of electrons. They go together in reactions called redox (reduction/oxidation). You cannot have a reduction without also having an oxidation.
In the reaction where NO₃^- is reduced to NO, nitrogen changes from a higher oxidation state (+5 in NO₃^-) to a lower oxidation state (+2 in NO). This reduction process involves gaining electrons and therefore is considered a reduction reaction.
it is the oxidation of Magnesium into Magnesium oxide which appears as a white powder.That is classified as a redox reaction, a term which is a contraction of reduction-oxidation. The magnesium is oxidized and the oxygen is reduced. The terms refer to the transfer of electrons. Electrons have a negative charge, so a recipient of electrons, such as oxygen is reduced in the sense that its charge becomes negative.
Ions are the particles that allow electrolysis to occur. Positively charged cations and negatively charged anions move towards the electrodes to undergo oxidation and reduction reactions, respectively, during the electrolysis process.
Well, let's think about it for a moment. The magnesium is being oxidized by the oxygen in the air. The oxygen is being reduced by the magnesium. Sounds like redox to me. More generally, a redox reaction is any reaction in which the oxidation state of the materials changes. In this case magnesium is going from 0 to +2 and oxygen is going from 0 to -2, so yes, it's a redox reaction.
