They need to be confronted with a chemical that will make them react and you might need to try different chemicals.

Answer:
Lithium has a melting point of 180.54 C, a boiling point of 1342 C, a specific gravity of 0.534 (20 C), and a valence of 1. It is the lightest of the metals, with a density approximately half that of water. Under ordinary conditions, lithium is the least dense of the solid elements.
Appearance: soft, silvery-white metal
Atomic Number: 3
Atomic Radius (pm): 155

Explanation:
The cold drink chiller is a cold substance which is inserted into a bottle of drink which contains warm liquid particles at a particular temperature.
Once the drink chiller is inserted, the liquid molecules around the drink chiller become cooler, denser and sink away from the drink chiller. Other warmer, less dense molecules of the liquid drink now replaces them around the drink chiller.
A convection current is thus set up for as long as the drink chiller is working.
If the specific rotation of (r)-2-butanol is −13.5° then
the specific rotation of (s)-2-butanol is simply the opposite in sign 13.5°. In
a 3:1 mixture of (s):(r) 2-butanol, 75% is (s) while 25% is r, so the specific
rotation of the mixture is:
mixture rotation = 0.75 * (13.5°) + 0.25 * (- 13.5°)
<span>mixture rotation = 6.75°</span>
