Question

The reaction given below is an example of:
$Ba\left(OH{)}_2\right(s)+2CuCNS(s)\to Ba(CNS{)}_2\left(aq\right)+2CuOH\left(s\right)$

• A. Combination Reaction
• B. Decomposition Reaction
• C. Displacement Reaction
• D. Double displacement Reaction

Answer 1

The correct option is D Double displacement Reaction

The above reaction is a double displacement reaction. In double displacement reaction the two compounds react with each other, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds.
