The uranium used for nuclear fuel exists in nature in several minerals. calculate how many moles of uranium are in 8.00 moles of the following: 1. carnotite, k2(uo2)2(vo4)2 • 3h2o 2. uranophane, cau2si2o11 • 7h2o 3. autunite, ca(uo2)2(po4)2 • 10h2o

For calculating the number of moles of uranium, we can count how many atoms of uranium exist in 1 molecule of the given, and multiply this by the given 8.00 moles.
Carnotite contains (UO2)2, meaning that it has 2 U atoms. Multiplying by 8 gives 16 moles of uranium.
Uranophane contains U2, meaning it has 2 U atoms. Multiplying by 8 gives 16 moles of uranium.
Autunite contains (UO2)2, meaning it has 2 U atoms. Multiplying by 8 also gives 16 moles of uranium.
Therefore, in 8 moles of all 3 compounds given, there are 16 moles of uranium.

Determine the  wavelength of light emitted when an electron  in an li2+ ion  makes a transition from an orbital with n  =  6 to an orbital with n  = 5.

Green is technically every other color but green but the other wavelengths of the other colors get absorbed by the object and the wavelength of the color green gets reflected
