a) Oxidation
b) reduction
Answers
Explanation:
(a) Oxidation (b) Reduction. (a) Oxidation: A chemical reaction in which a substance gains oxygen is called oxidation. ... (b) Reduction: A chemical reaction in which a substance loses oxygen is called reduction. ZnO + C → Zn + CO, ZnO is reduced to Zn. CuO + H2 → Cu + H2O, CuO is reduced to Cu
Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases
which an element combines with oxygen. Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium. ... And, each O2 molecule gains four electrons to form a pair of O2- ions.
Reduction
Reduction, any of a class of chemical reactions in which the number of electrons associated with an atom or a group of atoms is increased. The electrons taken up by the substance reduced are supplied by another substance, which is thereby oxidized.
