n = Vc and V = n/c = 0.642 mol / 1.08 mol/l = 0,59344.. l
Answer:
The one element is substituted in place of other element in compound.
Explanation:
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
For example:
Consider the reaction between zinc and silver nitrate. In this chemical reaction the zinc is substituted in place of silver in silver nitrate compound.
Chemical equation:
2AgNO₃ + Zn → ZnNO₃ + 2Ag
The starting material consist of compound ( AgNO₃) and pure element (Zn).
After reaction a new compound ( ZnNO₃) and pure element (Ag) is generated.
