your answer may be found on a website called "Thought.co"
once you get there just search "Examples of Chemical Reactions in Everyday Life" and it will give you some ideas :)
Answer:
Explanation:
The elements in Group I of the periodic table are called alkali metals. They are called alkali metals because they react with water to form alkali solutions. These metals are very reactive; hence they have to be stored under oil to protect them from corrosion by air and waterwaterwater
Explanation:
In a double displacement reaction, there is an actual exchange of partners to form new compounds.
The reaction is given as shown below:
AB + CD → AD + CB
One of the following conditions serves as the driving force for a double replacement reaction:
- Formation of an insoluble compound or precipitate
- Formation of water or any other non-ionizing compound
- Liberation of a gaseous product.
They make the symbols individual
