Quartz is a substance because the material has uniform properties throughout and is held together via chemical bonds.
The atom contain 6 neutrons, if that's the question
Answer: m/s^2 (metre per second square)
Explanation:
Acceleration is the rate of change in velocity per unit time. The standard unit of measurement for acceleration is m/s^2 (metre per second square).
It can be derived from:
Acceleration = velocity / Time
Acceleration = (metre per second / second)
Acceleration = metre per second square.
In short form, it is written as m/s^2
D) It is unlikely that a specific cause can be determined, but the treatment would likely be the same in either case
Answer:
In simple words, in an open system, the system that has external interactions. Such interactions can take the form of information, energy, mass etc. So keeping this definition in mind, the law of conservation of mass in open system is difficult because when chemical reaction takes places things change form and some things are released as energy, That energy than escapes the system and interacts with other surrounding. This is why it is difficult to demonstrate Law of Conservation of Mass because the changes in mass due to chemical reaction cannot be accounted for properly since the lost mass (in form of energy) was lost to environment.
Whereas, in closed system, all components occur inside a closed container or something where external interactions are minimal to none so the energy lost due to chemical reaction does not escape the system thus it can be accounted for properly to demonstrate the law of conservation of Mass.
Explanation:
Too many words but should get the point across hopefully!
