Answer:

B. Excited state

Explanation:

Energy levels higher than the ground state are called the excited states. This concept is based on the premise that electrons can move round the nucleus in certain permissibe orbits or energy levels.

The ground state is the lowest energy state available to the electron. This is usually the most stable state.

The excited state is any level higher than the ground state. An electron in an energy level has a definite amount of energy associated with it at that level.

Marrrta [24]

Long term because if you leave something out to be weathered then it can’t be unweathered because of the drastic change of the object.

What volume in litres will 38gr of F2 occupy at 0.999 bar and 273 K

FrozenT [24]

Answer:

$V=22.68L$

Explanation:

Hello,

In this case, we use the ideal gas equation to compute the volume as shown below:

$PV=nRT\\\\V=\frac{nRT}{P}$

Nonetheless we are given mass, for that reason we must compute the moles of gaseous fluorine (molar mass: 38 g/mol) as shown below:

$n=38 g *\frac{x}{y} \frac{1mol}{38 g} =1mol$

Thus, we compute the volume with the proper ideal gas constant, R:

$V=\frac{1mol*0.083\frac{bar*L}{mol*K}*273K}{0.999bar} \\\\V=22.68L$

Best regards.
