3. Name and define the four important types of chemical
reactions.
Answers
Explanation:
There are five types of chemical reactions :
1. Combination or Synthesis Reaction: Two or more simple substances combine to form a product which is more complex than the substances is called Combination or Synthesis Reaction.
____________________________
2. Decomposition Reaction: A reaction where a single compound breaks into two or more elements are called Decomposition Reactions.
____________________________
3. Displacement Reaction: When an element reacts with a compound and takes the place of another element in that compound then this type of reaction is called Displacement Reaction.
____________________________
4. Acid Base Reaction: When an acid reacts with an alkali salt the product is a metal salt and water, this type of reaction is Acid Base Reaction.
____________________________
5. Combustion Reaction: When a hydrocarbon reacts with oxygen to produce carbon dioxide and water then the Combustion Reaction takes place.
hope it helps u ✌
Different Types of Chemical ReactionsThe types of chemical reaction are:-
- Combination reaction
- Decomposition reaction
- Displacement reaction
- Double Displacement reaction
1. Combination Reaction - A reaction in which two or more reactants combine to form a single product is known as a combination reaction.
2. Decomposition Reaction - A reaction in which a single compound breaks into two or more simpler compounds is known as a decomposition reaction.
3. Displacement Reaction - A chemical reaction in which a more reactive element displaces a less reactive element from its aqueous salt solution.
4. Double Displacement Reaction - A chemical reaction in which ions gets exchanged between two reactants which form a new compound is called a double displacement reaction.
