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

What did Niels Bohr describe electrons in his atomic model
Bess [88]

Neils bohar proposed his atomic model in 1913.

He describe that's electron travel in a circular orbit surrounds the neuclus of an atom.each orbit has quantized energy and size. Energy is transmitted when an electron jumps from one to other orbit near to nucleus.and it absorb energy when it jumbs away from nucleus.he also said that these electrons are restricted to fixed orbits. In excited state of electron, they absorb or emitt photon with specific wavelength.

If 4.168 kJ of heat is added to a calorimeter containing 75.40 g of water, the temperature of the water and the calorimeter incr
Alinara [238K]

Answer:

The value of  the heat capacity of the Calorimeter  C_c = 54.4 \frac{J}{c}

Explanation:

Given data

Heat added Q = 4.168 KJ = 4168 J

Mass of water m_w = 75.40 gm

Temperature change = ΔT = 35.82 - 24.58 = 11.24 ° c

From the given condition

Q = m_w C_w ΔT + C_c ΔT

Put all the values in above equation we get

4168 = 75.70 × 4.18 × 11.24 +  C_c × 11.24

611.37 =  C_c × 11.24

C_c = 54.4 \frac{J}{c}

This is the value of  the heat capacity of the Calorimeter.
