Answer
Answer:
Li + ZnCO3 →
Explanation:
Step1: Understand activity - series concept
In a single - displacement reaction, a more reactive element can displace a less reactive element from its compound.
Step2: Analyze each option
- For Pt + FeCl3 →: Pt is less reactive than Fe according to the activity series, so Pt cannot displace Fe.
- For Mn + CaO →: Mn is less reactive than Ca, so Mn cannot displace Ca.
- For Li + ZnCO3 →: Li is more reactive than Zn. Li can displace Zn from ZnCO3.
- For Cu + 2KNO3 →: Cu is less reactive than K, so Cu cannot displace K.
