Answer: 23158.7J/mol
Explanation: Kinetic energy is the energy possessed by a body by virtue of its motion.
R= gas constant= 8.314 J/Kmol
T= temperature in Kelvin = 25 ° C = 25° C+273= 298 K
K.E = 23158.7 J
n= no of moles = 1 mole
Thu K.E per mole will be= 23158.7 J/mol
Answer:
Depends on different states.
Explanation:
The wavelength of the photon that is emitted from the atom during the transition depends on the transition from different states. If the photon is emitted from n=4 state to n=3 state, the wavelength of photon is 1875 while on the other hand, if the photon is emitted from n=5 state to n=3 state, the wavelength of photon is 1282. If the photon is emitted from n=3 state to n=2 state, the wavelength of photon is 656.
Answer:
136
Explanation:
The Mass Number is the combination of the amount of Protons and Neutrons in an element, so if the total mass is 222, and the amount of protons is 86, then you can do 86 + x = 222 to find that x is equal to 136
