(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.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
