Answer: its a single replacement reaction
<span>Water molecules form a complex with metal ions (usually a 6-coordinate complex). And the high charge density on a metal ion draws electrons away from the water molecules, making the O-H bonds more polar than normal. This allows the dissociation of the protons, making solutions of most metal ions acidic</span>

Taken the quiz, and got them all correctly answered!
Have a good day. <span />
There are few elements that can form 12 electron rather
than the usual 8. Therefore these are the possible answers:
Sulfur = 2Na + S --> Na2S <span>
Selenium = 2Na + Se --> Na2Se
<span>Tellurium = 2Na + Te --> Na2Te</span></span>
