The number of energy levels to which an electron can jump depends on the amount of energy the electron possesses. Each energy level has a specific amount of energy an electron needs to have before it can be in there. So, if an electron doesn't have enough energy to be in that energy level then it won't jump to that higher level.

Answer:

amount of the energy that the electron absorbs.

Explanation:

According to Bohr's postulates, electron present in the energy levels can jump to their higher energy levels on absorbing energy and also come back to their orbital by the radiating the absorbed energy.

<u>Thus, the number of the energy levels to which the electron can jump depends upon the amount of the energy that the electron absorbs.</u>

6) How should the conditions be changed to prevent the volume of a given mass of gas from expanding when its mass is increased
JulijaS [17]

Answer: increase pressure and decrease temperature.

Explanation:

Increasing pressure uses force to make the gas molecules come closer together. (Decreasing pressure allows the molecules to spread out) Decreasing temperature will also cause the molecules of gas to come together closer. (Heat excites molecules causing them to spread out and therefore expand)

Yellow cake is a uranium ore that contains about 75% U3O8 (842 g/mol), and can be further refined to extract pure uranium. How m
alex41 [277]

Answer : The correct option is, (5) 5.5 kg

Explanation :

As we are given that yellow cake is a uranium ore that contains about 75 % U_3O_8. That means,

Mass of U_3O_8 = 75 g

Mass of yellow cake = 100 g

Molar mass of uranium = 238 g/mol

Molar mass of U_3O_8 = 842 g/mol

First we have to calculate the mass of pure uranium.

As, 842 g of U_3O_8 contains 3\times 238g of pure uranium

So, 75 g of U_3O_8 contains \frac{75}{842}\times 3\times 238g=63.59g of pure uranium

Now we have to calculate the mass of yellow cake.

As, 63.59 g of pure uranium present in 100 g of yellow cake

So, 3.5 kg of pure uranium present in \frac{100g}{63.59g}\times 3.5kg=5.5kg of yellow cake

Thus, the mass of yellow cake processed to produce 3.5 kg of pure uranium must be, 5.5 kg
