How many electrons are taken up by an oxidant in the 1st halfreaction (oxidant reaction),and how many electrons are given free by a reductant in the 2st halfreaction (reductant reaction)
Reversing the equation gives the oxidation half reaction. Doing this changes the sign on the voltage, not the magnitude.
Burning of fossil fuels is an oxidation reaction.
The reaction equation between heptane and potassium permanganate is: C7H16 + 19KMnO4 + 40H2SO4 → 7MnSO4 + 19K2SO4 + 16H2O + 7CO2. This reaction is an oxidation reaction where heptane is converted to carbon dioxide, water, and other byproducts.
That is called a chemical equation. It represents the reactants, products, and their ratios in a chemical reaction.
oxidation
The oxidation half-reaction for the given equation is: Fe → Fe2+ + 2e-. This represents the loss of electrons from iron (Fe) to form iron ions (Fe2+).

Oxidation
Equations that separate the oxidation from the reduction parts of the reaction
The given chemical equation represents a redox reaction, specifically a reduction-oxidation reaction. It involves the transfer of electrons between iron (Fe) and hydrogen (H) to form different compounds.
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.
The reaction equation for the oxidation of acetylene (C2H2) with nitrous oxide (N2O) is: 2C2H2 + N2O -> 2CO2 + H2O + N2
The ionic equation for the reaction between nitric acid (HNO3) and iron (Fe) is: 3H+ + Fe -> Fe3+ + 3/2H2 This equation represents the dissociation of nitric acid into H+ ions and the oxidation of iron to Fe3+ ions.
Reversing the equation gives the oxidation half reaction. Doing this changes the sign on the voltage, not the magnitude.
A redox reaction can be identified in a chemical equation by observing the transfer of electrons between reactants. Look for changes in oxidation states of elements and the presence of both reduction and oxidation half-reactions.
