Which of the displacement reactions below occurs as written (don’t worry about balancing)?
1. Na+ + Zn ! Na + Zn2+
2. Fe3+ + Ag ! Fe + Ag+
3. None of the reactions occurs as written.
4. Ca2+ + Au ! Ca + Au+
5. Fe3+ + Mg ! Fe + Mg2+
Update:Which of the following reactions is correct?
1. Na+ + Zn = Na + Zn2+
2. Fe3+ + Ag = Fe + Ag+
3. None of the reactions occurs as written.
4. Ca2+ + Au = Ca + Au+
5. Fe3+ + Mg = Fe + Mg2+
