A. This is an example of a combustion reaction


B. Copper metal will be a product


C. No reaction will occur because Cu is more reactive than Al


D. One product will be AlCl3


E. AlCl2 will be producedChoose all of the statements that are true about this single replacement reaction: Al + CuCl2 ?
B and D





2Al + 3CuCl2 === 3Cu + 2AlCl3





Single replacementChoose all of the statements that are true about this single replacement reaction: Al + CuCl2 ?
Aluminum metal is more reactive than copper, so it will be able to displace it from its compound. The complete balanced equation for this reaction is:





2 Al(s) + 3 CuCl2(aq) 鈫?2 AlCl3(aq) + 3 Cu(s)





Answers:





B. Copper metal will be a product


D. One product will be AlCl3
