Does Lewis structure show all electrons in an atom?
Answer:
No. It only shows valence electrons.
Answer:
A Lewis Structure is a very simplified representation of the valence shell electrons in a molecule. It is used to show how the electrons are arranged around individual atoms in a molecule. Electrons are shown as "dots" or for bonding electrons as a line between the two atoms

Explanation:
At a pressure of 505 kPa, the volume of a gas is 12.00 mL. Assuming the temperature remains constant,
at what pressure will the new volume be 8.00 mL?
Answer:
757.5 kPa
Explanation:
Boyle's law states that p1 * v1 = p2 * v2
v1 = 12 mL
v2 = 8 mL
p1 = 505 kPA
p2 = ?
(505)(12) = (p2)(8)
6060 = (p2)(8)
p2 = 757.5

Which waves have some electrical properties and some magnetic properties?
a. longitudinal waves
b. transverse waves
c. mechanical waves
d. electromagnetic waves
The waves which have some electrical properties, and some magnetic properties are called as electromagnetic waves. The correct answer is option d.
Electromagnetic waves are a type of wave that consists of both electric and magnetic fields oscillating perpendicular to each other and to the direction of wave propagation.
They do not require any medium to propagate and they can travel through a vacuum. These waves include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Therefore, option d. electromagnetic waves have some electrical properties and some magnetic properties.
