Decide whether a chemical reaction happens in either of the following situations. if a reaction does happen, write the chemical equation for it. be sure your chemical equation is balanced and has physical state symbols. situation chemical reaction
a strip of solid iron metal is put into a beaker of 0.072m cu(no3)2 solution. yes no a strip of solid copper metal is put into a beaker of 0.081m feso4 solution. yes no

Explanation:

Iron is more reactive than copper so if solid iron is introduced into a beaker containing copper nitrate solution, iron will displace copper from the solution forming solid copper while iron enters into solution as ions.

In the second case, if copper is introduced to a solution of iron, there won't be any reaction because copper is less reactive than copper and therefore will not displace iron from a solution of it's salts
