Full information about types of chemical reactions
Answers
1-combination reac.- where two or more elements combine and form a single product
2-displacement reac.-where more reactive element displace the other less reactive elemnt from its compound
3-double dispalcement rea.-where exchange of ions take place between two element and they form a precipitate so also called as precipitation reac.
4-decomposition reac.-where a compound decompose into its element
5-oxidation and reduction or redox reac..-in this reac. oxygen and hydrogen is added to an element to make it oxidize and reduction respectively. .okkk
Chemical reaction is a process of forming new substance from another substances due to bonding of two different substances. There are two main things in a chemical reaction: Product and reactant. Product is a new substance formed. And, reactant is chemical due to which/on which reaction occurs. Chemical reactions occurs when some chemicals are reacted with other chemicals. A new substance is formed when the different chemicals are mixed/added together. All the chemicals and Compounds which we see are formed due to process of chemical reaction. We know that, When two or more elements are bonded together, then the new substance compound is formed. The all compounds available naturally and artificially are formed due to bonding of two different elements i.e. Chemical reaction.
In a chemical reaction, the new substances are formed due to reaction/contact between two different substances. While chemical reaction, no atoms are destroyed nor new atoms are formed. Only, The atoms are rearranged in such a way that the the new substance is formed.
Chemical reactions are of 4 types: Synthesis, Decomposition, Single replacement , Double replacement.
- Synthesis reaction
A + B → AB (Simple compounds formation)
- Decomposition reaction
AB → A + B (Opposite of synthesis reaction)
- Single Displacement reaction
A + BC → AB + C (Any of chemical is displaced)
- Double displacement reaction
AB + CD → AD + BC
Because of various chemical reactions done by scientists and development in chemistry has bought major changes in the world today. Everyday, scientists try to discover new chemicals, new compounds, new elements by doing complex chemical reactions. All the material used for making objects are made by doing chemical reactions only.
Examples of Chemical reaction:
- CH4 + 2O2 → CO2 + 2H2O
- C4H6O6 + NaHCO3 → NaC4H5O6+ H2O + CO2
- Na + Cl → NaCl
- 2 H2O → 2 H2 + O2
- HBr + NaOH → NaBr + H2O
