Answer:
the atomic number is 5
the atomic mass is 11
Explanation:
The atomic number is the amount of protons inside the nucleus, and this number also equals the amount of electrons. Since it shows you the nucleus and the electrons, all you need to do is count the protons (positive charge inside the nucleus) or count all the electrons (negative charge outside the nucleus, in the rings) and you should have your atomic number.
As for mass, all you need to do is count all the protons and neutrons inside the nucleus and add them up. Protons = 5, Neutrons = 6. (you add them since the equation for atomic mass is Atomic Mass = Protons + neutrons. This works every time)
5+6= 11, so your atomic mass is 11
I hope this helps :)
Answer:
Difference of path length
Explanation:
When we look into glass of ice tea, from top to bottom path length will be more as compared to when we look from side of the glass.
According to Beer Lambert law, absorbance is proportional to the path length. Path length is the distance that light travels through the material.
More path length will lead to more absorbance of light and more the absorbance more the darker tea looks.
Moreover, tea is a homogeneous solution, therefore, concentration of will be same through out the solution. Since, concentration is same, therefore, the effect of gravity will be also be same on all particles.
Therefore, difference in path length is responsible .
So, the correct option is option a, difference in path length
