1) name one specific instance in which single displacement reactions can be useful.
2) zn + cucl --> cu + zncl2
in this reaction, a solid would be formed from the copper. what is the solid known as a ___________
please help me
To the first part, use #2 rxn as an example. #2 is a single replacement reaction.
For #2, the field is wide open for an answer. I would try ppt but other answers will fit there too. And I might note that I don't like the wording. A solid would be formed from CuCl but not from Cu. The equation isn't balanced. It's also a redox reaction.
