The freezing point depression is a colligative property which means that it is proportional to the number of particles dissolved.
The number of particles dissolved depends on the dissociation constant of the solutes, when theyt are ionic substances.
If you have equal concentrations of two solutions on of which is of a ionic compound and the other not, then the ionic soluton will contain more particles (ions) and so its freezing point will decrease more (will be lower at end).
In this way you can compare the freezing points of solutions of KCl, Ch3OH, Ba(OH)2, and CH3COOH, which have the same concentration.
As I explained the solution that produces more ions will exhibit the greates depression of the freezing point, leading to the lowest freezing point.
In this case, Ba(OH)2 will produce 3 iones, while KCl will produce 2, CH3OH will not dissociate into ions, and CH3COOH will have a low dissociation constant.
Answer: Then, you can predict that Ba(OH)2 solution has the lowest freezing point.
I think the correct answer from the choices listed above is the second option. If a mixture of two metals was separated based on one metal's ability to allow electricity to pass, then the property that was important would be conductivity. <span> It is the ability to conduct electricity.</span>
Answer:
2KClO3--------->2KCl + 3O2
Answer:
ya thats right
Explanation:
here is one explanation i found on the web:
Answer: The true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".
Explanation:
The electric force is due to the forces acting between the charges. The magnetic force is the force exerted between the magnets or moving charged particles.
The electromagnetic force is created by the magnetic field and the electric field.
The magnetic force is related to the electric force. These forces are different aspects of single electromagnetic force. The moving charge produce the magnetic force. The moving magnet produce the electric forces. The interplay of electric field and the magnetic force is the basis for motor.
Motor converts the electrical energy into mechanical energy. The operation of a motor depends on the relationship between electric and magnetic forces.
Therefore, the true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".
