A metal M displaces zinc from zinc chloride solution. This shows that
M is more electronegative than zinc
Zinc is above hydrogen in the series
M is more electropositive than zinc
Electrons flow from zinc to M
Vysvětlení
M is able to displace Zinc from Zinc Chloride because it is more electropositive than Zinc.
