Extracted text: 1. A student tried to solve the following problem by selecting the tile as shown. What, if anything, did the student do wrong? 2AGNO3 (aq) + Cu (s) → 2Ag (s) + Cu(NO3)2 (aq) How many moles of silver nitrate (AGNO3) are needed to produce 6.75 moles of copper (II) nitrate (Cu(NO3)2) upon reacting with excess copper (Cu)? 6.75 mol Cu(NO32 1 mol Cu(NO3)2 2 mol AGNO3 A. The student chose the wrong tile to solve the problem. O B. The student chose the correct tile, but needs to flip the tile to make the units cancel. O C. The student chose the correct tile, but needs to add a second tile to finish the solution. O D. There is nothing wrong. The problem is ready to be solved.
