C. 1.0 mol/kg sodium phosphide (Na3P)<span>
This is because it will produce 4 ions, and thus has the highest molalitiy. (more particles in solution lowers the freezing point)

The type of motor that allows for constant speed regardless of load are called Geared Speed Control motors. This type of motor has a tachometer feedback device attached at the rear of the motor that gives constant feedback to the speed controller giving the advantage of constant speed regardless of load. The tachometer allows for varied frequency delivery to the motor to maintain pre-set output speed.
Answer:
liquid, solid, and gas. A heating curve shows how the temperature changes as a substance is heated up at a constant rate.
Explanation:
Answer: Wave speed= frequency x wavelength
=20 x 3
=60 m/s
