Combination Reaction
A combination reaction is a type of chemical reaction wherein two or more substances combine to form a single compound. In this reaction, the reactants are usually elements or simple compounds, and the product is a more complex compound.
Oxidation and Reduction
Oxidation and reduction are two types of chemical reactions that involve the transfer of electrons between two or more substances. Oxidation is the loss of electrons, while reduction is the gain of electrons. In some cases, combination reactions may also involve oxidation and reduction.
Explanation
In the given reaction, 2Ca + O2 = 2CaO, two substances, calcium (Ca) and oxygen (O2), combine to form a single compound, calcium oxide (CaO). Since there is no transfer of electrons between the reactants and the product, this reaction is a combination reaction.
Moreover, the reaction does not involve any change in the oxidation state of the reactants or the product. Calcium is in its +2 oxidation state, while oxygen is in its -2 oxidation state in both reactants and product. Hence, there is no oxidation or reduction taking place in this reaction.
Therefore, the given reaction is a combination reaction and does not involve oxidation and reduction.
