How many types of chemical reations are there? Explain in detail about it?
Answers
There are four types of chemical reaction... they are as follows..
1. Combination Reaction: The reaction in which two or more elements combine with each other to make one or more compound.
2. Decomposition reaction : Sorry but I don't know this explanation....
3. Displacement reaction: A more reactive metal displace a less reactive metal from its compound.
4. Double Displacement Reaction: Sorry but I don't know it's explanation
Hope this answer will help you....

Answer:
five
Explanation:
Combination/Synthesis Reactions: two or more substances combine to form a new compound (A+X->AX). Includes, but is not limited to, the reactions of elements with Oxygen and Sulfur; the reactions of metals with Halogens; and Synthesis reactions with Oxides.
Decomposition Reactions: a single compund undergoes a reaction that produces two or more singular substances (AX->A+X).
Single Replacement Reactions: when a substance in a compund is replaced by a substance outside of the compound (A+BX->B+AX). Possible replacements include: metals by another metal; Hydrogen in water by metal; Hydrogen in an acid by a metal; and Halogens by more active Halogens.
Double Replacement Reactions: when ions of two compounds exchange places in aqueous solutions to form two new compunds (AX+BY->AY+BX). One of the compounds formed is usually a precipitate, an insoluble gas that bubbles out of the solution, or a molecular compound (usually water).
Combustion Reactions: when reactive elements combine with oxygen, releasing a large amount of energy in the form of light and heat (e.g. the burnin of wood, natural gas, and gasoline). The formula begins with "hydrocarbon + Oxygen -> [products]"
