Define Chemical reaction. What are the types of chemical reactions?
Answers
Answer:
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
pls make me as a branliest....
Answer:
Chemical reaction is a chemical change that occurs in the reactants to form the products.
The types of chemical reactions are:-
- Combination Reaction
- Decomposition Reaction
- Displacement Reaction
- Double Displacement Reaction
- Oxidation and Reduction Reaction
Combination:-
When two reactants react to form a single product is known as a combination reaction.
CaO + H2O ---> Ca(OH)2 + Heat
Decomposition:-
When one reactant break down into simpler products is known as decomposition reaction.
Oxidation and Reduction Reaction:-
When in a reaction something is oxidized and something is reduced,it can be called as oxidation and reduction reaction or redox reaction.
Oxidation happens when oxygen is added to something or hydrogen is reduced from something. And reduction happens when oxygen is reduced from something or hydrogen is added to something.
- CuO + H2 ---(Heat)---> Cu + H2O
