Explanation:
??
The pressure an ideal gas exerts on a sealed container of fixed volume is directly related to its temperature in degrees Kelvin. That is:
In this scenario:
Rearranging gives
Convert the given density in mg/dL into a quantity with unit of g/L. This is shown below,
(200 mg / dL) x (10 dL / L) x (1 g / 1000 mg) = 2 g/L
Multiplying this quantity with the volume given, 5L, gives an answer of 10g.
Uranium emits particles and rays spontaneously through this process called radioactive decay or radioactivity.
Is the process by which the nucleus of an unstable atom loses energy by emitting radiation, including alpha particles, beta particles. gamma rays and conversion electrons.
Answer:
An electron is in a region outside the nucleus, <u>has less mass than a proton and has a negative charge.</u>
Explanation:
Electrons are considered as a negatively charged particle, as they are surrounded by the kind of invisible force called the electrostatic force.
