Calculate the change in energy of the hydrogen atom

AI Thread Summary
A hydrogen atom transitioning from the n = 4 level to its ground state results in a change in energy calculated using the formula E = (-2.18 x 10^-18 J)(1/1 - 1/16). The calculation yields E = -2.04378 x 10^-18 J, indicating a loss of energy during the transition. The negative value signifies that energy is released as the atom moves to a lower energy state. The discussion seeks confirmation of the calculation's accuracy and understanding of the energy change concept.

7. A hydrogen atom makes an electronic transition from its n = 4 level to its lowest energy level. Calculate the change in energy of the hydrogen atom.

E = (-2.18 x 10^-18 J) (1/1 -1/16) + 2.04378 x 10^-18 J

Is this correct. If not, can you show me how to do it.
Thanks for the help.

E = (-2.18 x 10^-18 J) (1/1 -1/16) = - 2.04378 x 10^-18 J
The answer is negative because the atome loses evergy.

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
