Question

predict the product that forms in the synthesis reaction between potassium metal and iodine gas. provide the balanced chemical equation for the reaction. explain your reasoning.

Answer 1

K + I -> KI
Potassium (wants to lose 1 electron) reacts with Iodine (wants to gain 1 electron) to satisfy both element's octet, forming a salt, potassium iodide
This is the same case for NaCl, just different elements. Hope this helped.
