*( Flying AirplaneWalking & RunningCyclingRollercoastersHydro-Power Plants )*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.

An atom has 8 protons, 9 Neutrons, and 10 electrons. What is the mass number?
Answer:
17
Explanation:
Mass number = # of protons + # of neutrons
Mass number is calculated using ONLY protons and neutrons. Electrons are not in the count.
Thus, we simply add them together: 8 + 9 = 17
This element is Oxygen - 17.

does sodium chloride retain any characteristic of sodium or chlorine?
Answer:
When this occurs, sodium will donate an electron (which is a negatively-charged particle) to chlorine. This makes sodium slightly positive and chlorine slightly negative. Opposite charges attract, right? So then, sodium ions will attract chloride ions and form an ionic bond.
