Answer:
yes, yes, no, no, no
Step-by-step explanation:
magnesium will react with copper nitrate to produce magnesium nitrate in a single replacement reaction
magnesium will react with silver nitrate to produce magnesium nitrate in a single replacement reaction
there is no displacement reaction that can occur with magnesium nitrate because both contain magnesium ions and there is no other metal that can replace magnesium in the compound
for the last two, no displacement reaction will occur because magnesium is not more reaction than lead or zinc
