sodium element is likely to have the highest thermal conductivity
Answer:
The given compound cannot be cocaine.
Explanation:
The chemist can comment on the nature of compound being cocaine or not from the depression in freezing point.
Depression in freezing point of is related to molality as:
Depression in freezing point = Kf X molality
Where
Kf = cryoscopic constant = 4.90°C/m
depression in freezing point = normal freezing point - freezing point of solution
depression in freezing point = 5.5-3.9 = 1.6°C
1.6°C = 4.90 X molality

we know that:

therefore
moles = 0.327X0.008 = 0.00261 mol


The molar mass of cocaine is 303.353
So the given compound cannot be cocaine.
It has a fixed mass
it does not change with the shape of the container
it cannot be compressed
it has fixed atom and molecules and limited to very small displacement
only vibrational motion occur in the molecules of solid .
Is a potential to provide effective treatment with fewer side effects than a traditional therapy.
The answer is Velocity and potential energy. Kinetic energy is the total energy of a system or an object in motion and requires movement.
