Great work! 3. Pick a "for every" statement about copper and silver in this balanced reaction. 29 47 Cu Ag Copper 63.55 Silver 107.87 Hint: The correct balanced equation is Cu + 2A9NO, → 2Ag + Cu(NO,)2 For every 1 mole of copper, the reaction makes 2 moles of silver. For every 1 mole of copper, the reaction uses up 2 moles of silver. For every 1 mole of copper, the reaction makes 1 mole of silver. Submit Answer 3/3 submissions remaining Score:
