out point out the difference between 1. oxidation and reduction and 2. combination and decomposition
Answers
Explanation:
The basic differences between Oxidation and Reduction are :-
Oxidation is the process of loss of electrons whereas Reduction is the process of gain of electrons.
Oxidation can also be gaining of oxygen atoms whereas Reduction is loss of Oxygen atoms.
Oxidation can also be loss of Hydrogen atoms but Reduction is the gain of Hydrogen atoms.
Oxidation State increases when Oxidation occurs while Oxidation state decreases when Reduction occurs.
Oxidation increases the positive charge of a chemical species but Reduction increases the negative charge of a chemical species.
2.Combination reaction:-
It is a chemical reaction in which two or more reactants combine with each other to form a new single product.
It releases heat during the chemical reaction.
This means that it is exothermic .
Examples :-
1) 2H₂ + O₂ ---->2H₂O
2) 2Mg + O₂ --->2MgO
Decomposition reaction:-
It is a chemical reaction in which one reactant breaks down into simpler compounds.
It absorbs heat from the surroundings during the chemical reaction.
IN other words , it is endothermic .
Examples :-
CaCO₃ ===> CaO + CO₂
2H₂O ===> 2H₂ + O₂

and decomposition
1.Oxidation is a reaction that removes an electron from a substance; reduction is a reaction that adds electrons to a substance
2.In a combination reaction, the reactants combine to form the product. In a decomposition reaction, one reactant can form two or more products by the breakage of bonds. ... In a combustion reaction, a hydrocarbon is combined with oxygen to produce carbon dioxide and water as well as ample amounts of energy.
