Chemical decomposition is the process of simplifying or breaking down a single chemical entity (normal molecule) into two or more fragements.

Chemical decomposition is the opposite of Chemical synthesis/ Combination reaction

General reaction formula : AB -> A + B

example:
chlorine + potassium iodide → potassium chloride + iodine

Cl2(aq) + 2KI(aq) → 2KCl(aq) + I2(aq)

The reaction mixture turns darker and iodine solution forms.]]> 2021-11-15 01:17:01 UTC https://padlet.com/Huisi/ip3l52ac14kyz9x5/wish/1889918473 Dalis https://padlet.com/Huisi/ip3l52ac14kyz9x5/wish/1889918637 Displacement reaction: one of the reactants (less reactive) is replaced by another reactant (more reactive)

A combustion reaction is a redox reaction in which a combustible substance reacts with an oxidizer to produce oxidized products and heat (exothermic reaction). In a combustion reaction, oxygen usually reacts with another substance to produce carbon dioxide and water.
Example: C₁₀H₈ + 12 O₂ → 10 CO₂ + 4 H₂O]]> 2021-11-15 01:17:57 UTC https://padlet.com/Huisi/ip3l52ac14kyz9x5/wish/1889920272 Ong Ding Jie https://padlet.com/Huisi/ip3l52ac14kyz9x5/wish/1889920374 Single replacement reaction where a element is substituted for another element in a compound

When an acid and base reacts with each other, generally the product of this reaction is salt and water. ]]> 2021-11-15 01:18:36 UTC https://padlet.com/Huisi/ip3l52ac14kyz9x5/wish/1889921597 Michelle https://padlet.com/Huisi/ip3l52ac14kyz9x5/wish/1889922754 Reaction between baking soda & vinegar.
-The reaction proceeds in two steps. The first reaction is a double displacement reaction, while the second reaction is a decomposition reaction.

NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
or
NaHCO₃ + HC₂H₃O₂ → NaC₂H₃O₂ + H₂CO₃

eg 2H2O electricity → 2H2 + O2

2.Combination reaction- two or more molecules are combined together chemically to form a new substance (compound)
eg Mg + O2 🡪 MgO

3.Combustion reaction-exothermic reaction which releases energy, generally in the form of heat
eg CH4 + 2O2 🡪 CO2 + 2H2O

4.Neutralization reaction-acid and base reacts with each other and form salt and water
eg NaOH(aq)+HCl(aq)→NaCl(aq)+H2O(l)

5.Single displacement reaction-more reactive metal displaces less reactive metal from its salt
eg2K + MgCl2 🡪 2KCl + Mg

6.Double displacement reaction- two aqueous ionic compounds exchange their ions (mostly cations) and produce two new compounds.
egKNO3 + AlCl3 🡪 Al(NO3)3 + KCl

7.Precipitation reaction-insoluble precipitate is formed
eg.AgNO3(aq) + KCl(aq)🡪 AgCl + KNO3(aq)

8.Redox reaction-oxidation and reduction take place simultaneously are called redox reactions

9.complex formation reaction-an exchange of coordinated water, directly bonded to the central actinide ion
