Answer: The correct answer is option B.
Explanation:
Average kinetic energy of the gas molecule is given by relation:
= Avogadro Number
T = Temperature of the gas in Kelvins.
R = Universal gas constant
With increase in temperature the kinetic energy of the gas molecule increases and vice-versa.
So, according to the question the explanation for a drop in temperature of the gas is decrease in average kinetic energy of the gas molecules.
Hence, the correct answer is option B.
The colored light emitted is energy and in order to emit energy the element should first obtain energy. The energy absorbed by the substance can be in the form of radiation, heat or electricity. Hope this answers the question. Have a nice day.
Answer:
4. A gene is introduced into salmon to make them grow twice as fast.
Answer:
3p⁶ 4s² 3d²
Explanation:
From the question given above,
The electronic configuration of the element ends with 3p².
Another element having 8 more electrons will have the following electronic configuration as illustrated below:
Step 1:
Complete the 3p orbital by adding 4 electrons:
3p² + 4 electrons = 3p⁶
Step 2:
Fill the 4s orbital. This is so because 4s has a lower energy level compared to 3d.
4s²
Step 3:
Fill the 3d orbital with the remaining electrons i.e 2
3d²
Summary:
The continuation of the electronic configuration of the element with 8 more electrons is:
3p⁶ 4s² 3d²
Answer:
response I believe
Explanation:
i'm pretty sure it's a response cause it's the animal responding to needing water and being thirsty
hope this helps! :)
