Answer:
The remote control sends low-energy infrared radiation to a light detector on the front of the television

Given,
Molality = .5M
We know, Kf = 1.86
Now,
Δ T = M x Kf
= 1.86 * 0.5
= 0.93 °C
Now,
Freezing point = Initial freezing point - Δ T
= 0°C - 0.93°C
= -0.93°C
So, the answer is A
Answer:
Beryllium Fluoride (BeF2) is an ionic compound
