An atom in an excited state contains more of what type of energy than the same atom in the ground state? An atom in an excited s
kupik [55]

Answer: An atom in an excited state contains more of kinetic energy than the same atom in the ground state.

Explanation:

Kinetic energy is the energy acquired by an object due to its motion. And, thermal energy is the internal energy of an object arisen because of the kinetic energy present within the molecules of the object.

Potential energy is the energy acquired by an object due to its position.

The total energy present at the center of mass of an object is known as mass-energy.

So, when an atom gets excited then it means it is gaining kinetic energy due to which it moves from its initial position after getting excited.

Thus, we can conclude that an atom in an excited state contains more of kinetic energy than the same atom in the ground state.

If 0.0714 moles of N2 gas occupies 1.25 L space, how many moles of N2 have a volume of 25.0 L? Assume temperature and pressure s
vfiekz [6]

Answer:

1.428 moles

Explanation:

If 0.0714 moles of N2 gas occupies 1.25 L space,

how many moles of N2 have a volume of 25.0 L?

Assume temperature and pressure stayed constant.

we experience it 0.0714 moles: 1.25L space

x moles : 25L of space

to get the x moles, cross multiply

(0.0714 x 25)/1.25

1.785/1.25 = 1.428 moles
