Answer:
atom
Explanation:
The sodium atom has a single valence electron that it can easily lose. (If the sodium atom loses its valence electron, it achieves the stable electron configuration of neon.) The chlorine atom has seven valence electrons and can easily gain one electron.
<span>Decreasing the temperature will decrease the pressure of a gas inside a closed cubical container.
In a closed container, the Volume (V) is fixed and the no of mole of the gas(n) are also fixed. So, we write the gas equation : PV = nRT
Here, V,R and n are constants.
So, Pressure is directly proportional to the temperature. Thus, on increasing the temperature, pressure will increase and on decreasing the temperature, the pressure will decrease.</span>
Your answer is: A. tetrahedral
Hope this helped! :D
Answer:
4.86 × 10^-7m
Explanation:
Wavelength = C/f
C (Speed) of light = 3 × 10^8
f = 6.17 × 10^14
Wavelength = (3 × 10^8)/ (6.17 × 10^14)
= 4.86 × 10^-7m
Answer:
B) separation by boiling points
Explanation:
According to the diagram depicted, crude oil is separated into its different units using boiling points.
- The boiling points of a compound is the temperature at which it begins to boil.
- The process of fractional distillation is used in the oil industry to separate crude oil into its components.
- When the boiling point of a oil fraction is reached, it becomes vaporized and rises within the column
