The relationship between diffusion to particle motion and collision in the gas and liquid phases

Chemistry
1 answer:
nlexa [21]3 years ago
4 0

Answer: In the gas phase using the example of the perfume in the air, the air very slowly separates the molecules of the perfume which allow them to spread to the olfactory system (sense of smell) to the individuals in the area. In this experiment, the particles moved very slow and we know this because it took a long time for the perfume smell to reach the back of the room. In the liquid phase using the example of the food dye in the cold and hot water, the food dye diffused a lot faster in the hot water because the particles were moving a lot faster and colliding more often and at an increased rate compared to the cold water where the food dye took a lot longer to diffuse in the water and the particle motion and collision was a lot slower and a lot less frequent

What is the molarity (M) of an 85.0-mL solution (total volume) containing 1.77 g of ethanol (C2H5OH)
Liono4ka [1.6K]

Answer: The molarity of solution is 0.453 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

where,

n = moles of solute

V_s = volume of solution in ml

moles of C_2H_5OH = \frac{\text {given mass}}{\text {Molar mass}}=\frac{1.77g}{46g/mol}=0.0385mol

Now put all the given values in the formula of molality, we get

Molarity=\frac{0.0385\times 1000}{85.0}

Molarity=0.453

Therefore, the molarity of solution is 0.453 M

dimulka [17.4K]

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.".
