In a single replacement reaction, why will one metal replace another metal in an ionic compound?
- A.
The metal will replace another metal if it has a smaller mass and thus is able to hit the ionic compound with a higher velocity and thus more energy.
- B.
The metal will replace another metal if it has a larger mass and thus is able to hit the ionic compound with more energy.
- C.
The metal will replace another metal if it can gain electrons more readily than the other metal.
- D.
The metal will replace another metal if it can lose electrons more readily than the other metal.
Correct Answer
D. The metal will replace another metal if it can lose electrons more readily than the other metal. -
