Since I cannot find the choices, I will tell you some of the benefits of electroplating in different industries. You can compare these benefits with the choices you have and choose the best fit.
1- Forms a protective layer to protect the material from the conditions of the atmosphere as the corrosion
2- Improves the appearance of some inexpensive materials and makes them look more appealing
3- Can enhance the electrical conductivity of materials
4- electroplating of zinc-nickel or gold can survive high temperatures
5- Sometimes hardens the material
6- Increases the thickness of the material
Answer: Option (d) is the correct answer.
Explanation:
Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.
So, when thermal energy is added to an object then kinetic energy within its molecules will also increase. As a result, temperature of the object will also increase due to increase in number of collisions between the molecules.
Therefore, we can conclude that the statement energy that is associated with temperature, describes thermal energy.
Answer:
B : 0.133 M
Explanation:
moles Li3N3 = 0.4 mol Li x (2 moles Li3N/6 moles Li) = 0.133 M

bent geometry of the water molecule gives a slight overall negative
charge to the oxygen side of the molecule and a slight overall positive
charge to the hydrogen side of the molecule. This slight separation of
charges gives the entire molecule an electrical polarity, so water
molecules are dipolar.</span>
