Hint: when Energy is released along with a product, such reactions are called exothermic reactions and striking match leads to friction generating more energy than that can be taken by particles resulting in flame.
Complete solutions step by step:
Head of match has Sulphur compound called antimony trisulphide and it also contains potassium chlorate. Sulphur compound is oxidized by potassium chlorate and releases energy. When a match is pulled over a surface that contains red phosphorus, there is an immediate reaction with potassium chlorate and enough energy required for activation of oxidation of Sulphur compound is released.
- when Energy is released along with a product, such reactions are called exothermic. During striking of a match, more heat energy is generated by friction than surrounding particles can take, resulting in flame.
Therefore the answer will be (C ), because energy is given out as the match burns describes chemical reaction.
Note: When energy is absorbed in reaction, such reactions are called endothermic reactions and when Energy is released along with products, such reactions are called exothermic reactions. Friction is responsible for creating heat When a match is pulled over a surface that contains red phosphorus, enough amount of energy required for activation of oxidation of Sulphur compound is released.
