Chemical Reactions and Equations

2. Substances that take part in a chemical reaction.
4. A more reactive metal displaces a less reactive metal from its salt solution.
8. Oxidation and Reduction of reactants taking place simultaneously.
9. Decomposition by passage of electric current.
10. Substances formed during a chemical reaction.
11. Slow Oxidation of Fats and Oils, resulting in foul odour and taste.
14. Energy is released along with formation of products.
16. Process in which the original substance loses its nature and identity to form new substance(s) with different properties.

1. Decomposition in the presence of sunlight.
3. Energy in the form of heat, light or electricity is absorbed to break down the reactants.
5. Single reactant breaks down to give simpler products.
6. Denotes that the reactant or product is present as a solution in water.
7. Deterioration of a metal caused by the action of substances like moisture and acids in its surroundings.
12. Mutually exchanged during a double displacement reaction.
13. Decomposition by heating.
15. Several reactants combine to form a single product.
