(fe(s)+cuso4((aq)+cu(s) this chemical equation represents a reaction

Answer : This chemical equation represents a single replacement reaction.

Explanation :

Single replacement reaction : It is defined as the reaction in which the most reactive metal displace the least reactive metal form its solution.

The given balanced chemical reaction is:

The given chemical reaction is a single replacement reaction because in this reaction, iron is most reactive metal than the copper. So, iron can displace the copper metal form its solution and it forms iron (II) sulfate and copper as a product.

Hence, the chemical equation represents a single replacement reaction.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

you need to have a picture of the atom that way we can answer it
