Question
2 RbNO3 + BeF2→ Be(NO3)2 + 2RbF
Single displacement
Double displacement
Decomposition
Synthesis
Hint:
Double displacement reaction can be termed as when two displacements take place in a reaction.
The correct answer is: Double displacement
The word displace means to push out. A more reactive element can displace a less reactive element out of its compound during a chemical reaction, this reaction is termed as displacement reaction. Double displacement reaction can be termed as when two displacements take place in a reaction. Also, it can be termed as chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products
2 RbNO3 + BeF2→ Be(NO3)2 + 2RbF Here, nitrate and fluoride are exchanged. It is a double displacement reaction.
