Answer:
The property of metals that is the result of light reflecting off the electrons is
A. shiny
Answer:
0.5 g/mL----- float
1.0 g/mL---- float
2.0 g/mL-----sink
Explanation:
Those objects will float whose density is less or equal to water density due to lower mass while those object will sink whose density is greater than water because the mass of the object is greater than water. So the density of the object i. e. 0.5 g/mL and 1.0 g/mL will float in the liquid because its density is lower than water which is 1 g/mL while the density of an object i. e. 2.0 g/mL is denser than water so it will sink.
Answer:
Explanation:
Ya que las cargas eléctricas opuestas se atraen, las moléculas de agua tienden a atraerse unas a otras, haciendo el agua "pegajosa," como lo muestra el diagrama del lado derecho. Cuando las moléculas de agua se atraen unas a otras, se unen. Esta es la razón del porqué se forman las gotas
It would be Rubidium chloride.
Answer:
Option (A)
Explanation:
Radioactivity is defined as a process in which an unstable atomic nucleus decays continuously and after a specific period of time changes into a much more stable element. During this time of decay, the nucleus emits charged particles (energy) which are known as the α, β and γ particles. These are often emitted in the form of electromagnetic energy and are very dangerous to health.
The radioactive elements decay at a certain rate which is commonly known as the half-life. Half-life is basically defined as the time required by a radioactive substance to decay half of its initial composition.
Thus, the correct answer is option (A).
