Answer:
I hope this helps
Explanation:
Lewis symbols, which are also known as Lewis dot diagrams or electron dot diagrams, are diagrams that represent the valence electrons of an atom. Lewis structures, also known as Lewis dot structures or electron dot structures, are diagrams that represent the valence electrons of atoms within a molecule.
Physical change. Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. ... Physical changes occur when objects or substances undergo a change that does not change their chemical composition.
Answer:
Explanation:
Given :
Mass of a bar of lead = 115.2 g
Initial water level 
= 25 mL
Final water level = 35.5 mL
Difference in the water level = 35.5 - 25
= 10.5 mL
= 
We know that when a body is submerged in water, it displaces its own volume of water.
Therefore, the volume of the lead bar = volume of the water displaced = 10.5 mL =
We know that mathematically, density is the ratio of mass of body to its volume.
Density of the lead bar is given by :
=

Hello mr/mrs (name) I unfortunately couldn't pay attention to the class due to some issues I had therefore I don't know what we are doing in class
OR
Hello mr/mrs (name) I could understand what we were doing in class I would like it if you could break it down more or explain better to me
OR just say something it had something to do with your internet such as
Hello mr/mrs (name) I didn't understand what you were saying during our class due to some of my internet issues I was have throughout the day. I hope you can explain what we did during the class.
Those may be some of my excuses I've used before
they have worked for me:)
I don't know if that helped?:/
The electrons that are in the outermost electron shell, also known as the valence shell, have more energy then those in the inner electron shells, I hope this helps<3
