Answer:
Displacement Reaction
Explanation:
Zinc replaces lead in Lead(ll) nitrate as zinc is more reactive than lead.
The ansewer is Boyle’s law
Calcium metal with chromium(III) chloride would react. Calcium metal is more reactive than chromium metal; therefore, putting calcium metal in chromium chloride would create a reaction, where as putting chromium metal in calcium chloride would not form any reaction.
C unbalanced force is occuring
Atomic radii increase when going down a group and decreases when going towards the anion periods. So A and D.
