Silver. For the most part only metals can have metallic bonding. Ammonium chloride has ionic bonding (poly-atomic cation + nonmetal=ionic bonding), iodine is a diatomic element so it will form a covalent bond with itself, and barium oxide has ionic bonding (metal+nonmetal or metal+poly-atomic anion=ionic bonding).
I hope this helps. Let me know in the comments if anything is unclear.
First, in this case, we define the K constant as the solubility of the solute in water divided by the solubility of the solute in ether.
K = (X grams of solute / 75 mL of ethyl ether) / (5 g of solute / 100 mL of water)
K = (X / 75) / (5 / 100)
1 = (X / 75) / (5 / 100)
5 / 100 = X / 75
0,05 = X /75
X = 0,05 × 75 = 3.75 g of solute that will be extracted by the ether
Thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated
