Answer the following questions.
Name the different types of chemical reactions.
Different types of chemical reactions are:
•Combination Reaction
•Decomposition or Dissociation Reaction
•Displacement Reaction
1.Combination Reaction:
Two or more reactants unite to form a single product.
General Form: A + B -> AB
Eg: S + O2 ---------> SO2
2.Decompostion Reaction
A single reactant is decomposed or broken down into two or more
products.
General Form: AB -> A + B
Eg: CaCO3 ----------> CaO + CO2
3.Displacement Reaction
A reaction in which one constituent displaces another and separates is called displacement reaction.
General Form : A + BC -> B + AC
Eg: Zn + 2 HCl ----------> H2 + ZnCl2
