Energy is released when an electron transitions from one energy level to another. In contrast, the same amount of energy is needed to carry out the process, the other way around, from the bottom elevation to the upper one.
What occurs when an electron transitions from one energy level to another?
- The energy of the electron drops when it changes levels, and the atom releases photons. The electron emits a photon when it transitions from a greater to a lower energy level. The energy emitted is precisely the energy that is lost when an electron moves to a level with less energy.
- An atom's electrons have negative energy. The electron must be given energy in order to be removed from the hydrogen atom, as shown by the negative sign. The quantity of energy in the atom will rise by supplying the electron with energy. Similar to how a ball on Earth chooses to rest in valleys rather than hills, the electron wants to spend the majority of its time at a lower energy level.
- For a brief period of time, the electron remains in an excited state. The energy required to bring the electron to its lower-energy state will be released when the electron transitions between excited and unexcited states.

Answer: reaction type is combustion
Explanation:
C6H14 + 19/2O2 ==> 6CO2 + 7H2O
Answer:
The new pressure in the balloon is 16.3 atm
Explanation:
Gay-Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant.
This law establishes that pressure and temperature are directly proportional quantities, that is to say that if the temperature increases the pressure increases and if the temperature decreases the pressure decreases.
Mathematically, Gay-Lussac's law states that, when a gas undergoes a constant volume transformation, the quotient of the pressure exerted by the gas temperature remains constant:
When you want to study two different states, an initial one and a final one, of a gas, you can use the expression:
In this case:
- P1= 14.7 atm
- T1= 273 K
- P2= ?
- T2= 303 K
Replacing:
Solving:
P2= 16.3 atm
<u><em>The new pressure in the balloon is 16.3 atm</em></u>
Answer:
Genes are segments of DNA that contain the code for a paticular protein that works in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Explanation:
<u>Answer:</u> The new volume of the balloon will be 583.5 L
<u>Explanation:</u>
To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.
The equation follows:
where,
are the initial pressure, volume and temperature of the gas
are the final pressure, volume and temperature of the gas
We are given:
![P_1=1.15atm\\V_1=3.60L\\T_1=20^oC=[20+273]K=293K\\P_2=5.40\times 10^{-3}atm=0.00540atm\\V_2=?\\T_2=-50^oC=[-50+273]K=223K](https://tex.z-dn.net/?f=P_1%3D1.15atm%5C%5CV_1%3D3.60L%5C%5CT_1%3D20%5EoC%3D%5B20%2B273%5DK%3D293K%5C%5CP_2%3D5.40%5Ctimes%2010%5E%7B-3%7Datm%3D0.00540atm%5C%5CV_2%3D%3F%5C%5CT_2%3D-50%5EoC%3D%5B-50%2B273%5DK%3D223K)
Putting values in above equation, we get:
Hence, the new volume of the balloon will be 583.5 L
