some important reactions and catalysts

.Two reactants mutually transfer their respective groups to form two new compounds in double decomposition reaction. The reaction CaCO3  CaO + CO2 is an example of Displacement Reaction
An insoluble precipitate is formed in precipitation reaction. In neutralisation reaction, an acid and a base combines to form a salt and water. Hydrolysis of sodium carbonate gives Sodium Hydroxide (NaOH) and Carbonic Acid (H2CO3)
Isomerisation reaction is also called Rearrangement reactions. It is common in organic compounds. Heat is released in Exothermic Reactions
Energy released or absorbed after completing a chemical reaction is called heat of reaction
, Photochemical reactions activates by absorbing sunlight. The branch of Chemistry, which study these reactions, is called Photochemistry
Catalysts alter the rate of any reaction without undergoing any change in itself. Such reactions are called Catalytic reactions. Biochemical catalysts are called Enzymes
The enzymes possess specific nature. Optimum temperature for their activity ranges from 298 K to 310K
2MgO + O22MgO Combination reaction
Zn + CuSO4  ZnSO4 + Cu Displacement reaction
Na2SO4 + BaCl2  BaSO4  +2NaCI Double decomposition reaction
AgNO3 + NaCI AgCl  + NaNO3 Precipitation reaction
NaOH + HCI  NaCI + 2H2O Neutralisation reaction
