Answer:
1) A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product). Such reactions may be represented by equations of the following form: X + Y → XY.
2) Decomposition is a type of chemical reaction. It is defined as the reaction in which a single compound splits into two or more simple substances under suitable conditions. It is just the opposite of the combination reaction.
Decomposition reactions can be classified into three types:
Thermal decomposition reaction. Electrolytic decomposition reaction. Photo decomposition reaction.
3) A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one element replaces an/other element in a compound. It can be represented generically as: A + B-C → A-C + B This will most often occur if A is more reactive than B, thus giving a more stable product.
4) A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
5) Reduction is a chemical reaction that involves the gaining of electrons by one of the atoms involved in the reaction between two elements. The term refers to the element that accepts electrons, as the oxidation state of the element that gains electrons is lowered.
6) Oxidation is any chemical reaction that involves the moving of electrons.Oxidation is the opposite of reduction.
7) Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.
8) An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat.
9) An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction.

Answer:
•reaction in which two or more reactants react to form a single product is called combination reaction.
•reaction in which a single product decomposes or breaks to for two or more products is called decomposition reaction.
•reaction in which more reactive metal displaces less reactive metal from its compound is known as displacement reaction.
•reaction in which there is an exchange of ions between the reactants are called double displacement reactions.
•if a substance gains oxygen or loses hydrogen during a reaction then the process is called reduction and the opposite for oxidation.
•when heat is released during a reaction along with the formation of the products it's said to be exothermic reaction.
•when heat is absorbed during a reaction then it is called endothermic reaction .
