1.	What are the main types of chemical ? Answer in brief
Answer» Explanation:Types Of Chemical Reactions Explanation General Reaction Combination reaction- Two or more COMPOUNDS COMBINE to form one compound. A + B → AB Decomposition reaction -The opposite of a combination reaction – a complex molecule breaks down to make simpler ones. AB → A + B Precipitation reaction- Two solutions of soluble salts are mixed resulting in an insoluble solid (precipitate) forming. A + Soluble salt B → Precipitate + soluble salt C .Neutralization reaction - An acid and a base react with each other. Generally, the product of this reaction is a salt and water. Acid + Base → Salt + Water COMBUSTION reaction- Oxygen combines with a compound to form carbon dioxide and water. These reactions are exothermic, meaning they give off heat. A + O2 → H2O + CO2 Displacement reaction- One ELEMENT takes place with another element in the compound. A + BC → AC + B
