The valence electrons of an element is usually determined by its atomic number. The valence elctrons are the electrons that have the highest energy level.
Fluorine has 7 valence electrons in the ground state.
<u>Answer:</u> The volume of the container is 
<u>Explanation:</u>
To calculate the volume of water, we use the equation given by ideal gas, which is:

or,

where,
P = pressure of container = 200 kPa
V = volume of container = ? L
m = Given mass of water = 2.61 kg = 2610 g (Conversion factor: 1kg = 1000 g)
M = Molar mass of water = 18 g/mol
R = Gas constant = 
T = temperature of container = ![200^oC=[200+273]K=473K](https://tex.z-dn.net/?f=200%5EoC%3D%5B200%2B273%5DK%3D473K)
Putting values in above equation, we get:

Converting this into cubic meter, we use the conversion factor:

So, 

Hence, the volume of the container is 
Answer:
Ethylene glycol
HOCH₂CH₂OH
Explanation:
For the molecules in the question, the viscosity will rise with the number of hydrogen bonds that can be formed.
A hydrogen bond is a week physical bond which is formed when hydrogen is found between atoms with high electronegativity (oxygen, nitrogen, fluorine):
O-H ··· O, N-H ··· O, N-H ··· O, O-H ··· N, F-H ··· F and so on.
Here we have have two compounds that can form hydrogen bonds (between themselves):
C) ethanol and D) ethylene glycol
Ethylene glycol have more hydroxide groups (-OH) than the ethanol so it will form more hydrogen bonds thus increasing its viscosity.
Explanation:
Vander waal forces are defined as the weak electric forces which tend to attract the neutral molecules towards each other in gases, liquefied and solidified gases. And, it is also present in all organic liquids and solids.
Vander wall forces are basically present in all type of molecules. More is the number of carbon atoms present in a molecule more will be the presence of Vander waal forces.
As a result, butanol will have strongest intermolecular force of attraction because it contains more number of carbon atoms and also it has more electronegative oxygen atom.
Whereas n-pentane will have the weakest intermolecular force of attraction between its atoms.
