Hello. In this prime, we're told the copper metal can be extracted from copper to oxide by displacing with aluminum. This process is also known as the thermite reaction. Copper and copper to oxide will be reduced while the aluminum will be oxidized, forming copper metal and aluminum oxide. For us to provide the balanced equation for this reaction are reacting. It's will be a woman of metal And copper two oxide. Given the name we know that the charge on copper is a two plus, we call that oxygen is in group six A. So well, for my use of the two minus charge, the two plus into minus bounce out. So the formula C U O, our products are copper metal and aluminum oxide. Aluminum is in group three. A form signs with a three plus charge. Oxygen's in group six. A form signs with a two minus charge Using the crossing method. This will become a two and a three. So we have a total plus six and minus six. So those will balance out formula then is A L +203. So we'll combine this all together. So we have aluminum metal reacting with copper to oxide form aluminum oxide and copper metal. So we're going to need to balance our aluminum's by adding a two out front. So we have two aluminums on both sides. We can balance the oxygen by putting a three out in front of the copper to oxide. Now, oxygen's are balanced. We have three coppers now on the reacting side and only one on the product side. So we'll put a three out in front of the copper to balance the copper. So this is our balanced reaction equation which corresponds then to answer C thanks for watching. Hope this helped.
