Molecules
Process
Reactivity
Definitions
Definition - A chemical reaction is a process in which one or more substances (Reactant) is converted to create new substances ( Product). - Kavya
Chemical reaction is the process of re-arrangement of molecules. When substances (reactant) react to form a new substance (product) , it is called a Chemical reaction. - Nehal
Chemical reactions are when 2 or more substances combine and react to form new substances, which also changes their molecular structure. - Shrimanyu
Reactivity
Many metals are reactive. They have a reactivity series which indicate how reactive/responsive they are.
aluminum is less reactive, it doesn't react with air and reacts mildly in water
Potassium is very reactive, it reacts vigourously with air and water
Reactions have different intensities, different elements have different reactions to substances.
Types of Chemical Reactions - A few basic types of chemical reactions are combination, decomposition, combustion, etc.
Combustion is the process of burning something with the help of oxygen.
Decomposition reaction is in which a single compound splits into two or more simple substances under suitable conditions. It is said that it is the opposite of Combustion.
Combination reaction is a reaction where two reactants are combined into one product.
