The given reactions are combination reaction, decomposition reaction, neutralization reaction, displacement reaction and double displacement reaction.
What is displacement reaction?
A displacement reaction is a chemical process during which a one more reactive element being replaced from its compound by a less reactive element.
What is combination reaction?
When A combination reaction occurs when one or more elements or compounds react together to generate a new chemical. Equations of the following kind are used to depict such reactions.
