Answer:

The electron moved down to an energy level and has an energy of

10.92 \times 10^{-19} \textsf{J}

Step-by-step explanation:

\textsf{initial energy level of electron}= 16.32 \times 10^{-19} \textsf{J}

\triangle E =\textsf{energy released}= 5.4 \times 10^{-19} \textsf{J}

A positive energy change means that the electron absorbs energy, while a negative energy change implies a release of energy from the electron.

Therefore, when an electron absorbs energy, the electron moves up to higher energy levels, and when an electron releases energy, it moves to lower energy levels.

\triangle E=E_2-E_1

\implies 5.4 \times 10^{-19} = 16.32 \times 10^{-19} -E_1

\implies E_1= 16.32 \times 10^{-19} -5.4 \times 10^{-19}

\implies E_1= 10.92 \times 10^{-19}

<u>Answer</u>:

The electron moved down to an energy level and has an energy of

10.92 \times 10^{-19} \textsf{J}

The Dakotas rented a minivan for their family vacation. When they returned
Ivahew [28]

Answer:

4 additional days.

Step-by-step explanation:

So the total charge is $575.

It costs $355 for 1 week of use of the van.

1 week is 7 days.

It costs $55 for each extra day of use of the van.

575=55d+355

d is for the unknown extra amount of days.

subtract 355 from both sides

220=55d

divide by 55 on both sides

4=d

So, the Dakotas used the van for 4 additional days. So in total the used the van for 4+7 days.

4+7=11 total days.

But the answer to the question is 4 days, because it specifically ask for additional days.
