Answer:
819 K
Explanation:
Given data
- Initial pressure (P₁): 1 atm (standard pressure)
- Initial volume (V₁): 250 mL
- Initial temperature (T₁): 273.15 K (standard temperature)
- Final pressure (P₂): 0.500 atm
- Final volume (V₂): 1500 mL
- Final temperature (T₂): ?
We can find the final temperature using the combined gas law.
Answer:
4 energy levels/rings
Explanation:
By the atomic model proposed by Niels Bohr, the electrons orbit around the nucleus in shells having different energy level each with the ability to contain a given maximum amount of electrons.
The closest shell to the nucleus named the K shell, can have a maximum of two electrons, the next shell known as the L shell can have 8 electrons while the next shell, M, can have a maximum of 18 electrons
The arrangement of the periodic table is based on the number and location of electrons such that elements in the 4th row (period 4 elements) have three completed energy levels/rings before, their valence ring making the total number of rings = 4 energy levels/rings.
Answer:
n chemistry, we talk about the attraction between protons (+) in the nucleus to the ... Because electrons are negatively charged, they are attracted to nuclei, which are ... Reasoning: There are the same number of energy levels/shells, but there are ... more distance between outer electrons resulting in a weaker attraction
Explanation:
<span>In a mechanical clock, the swinging of a pendulum causes the hands to move. The point of the pendulum in its swing have the least gravitational potential energy is at its original position.</span>
I think the minimum uncertainty in the electron's velocity if the location of a particular electron can be measured only to a precision of 0.058nm is d which is 2.2X10 5 m/s. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
