<span>The correct answer is because there are strong adhesive forces exist between glass and the water molecules. They're not as strong as let's say glue or similar adhesives, but are good and water connected to glass has bigger adhesivity then if it was inside of a wooden cup for example or a bowl.</span>
Your going to want to round 8.01 to 8.01 and change 3.127 rounded too 3.1
then u want to take 8.0 and 3.1 and times it and u will get 24.8 or 25
Answer:
a). P = 688 atm
b). P = 1083.04 atm
c).Δ G = 16.188 J/mol
Explanation:
a). Fugacity 'f' can be calculated from the following equations :
where, P = pressure , Z = compressibility
Now, the virial equation is :
........(1)
Also, PV=ZRT for real gases .......(2)
∴ 
So from the fugacity equation ,
Putting the value of P = 500 atm in the above equation, we get,
f = 688 atm
b). Given f = 2P
∴ P = 1083.04 atm
c). dG = Vdp -S dt at constant temperature, dT = 0
Therefore, dG = V dp

Δ G = 16.188 J/mol
The atom that has 7 valence electrons is A. fluorine.
It is in the halogens group.
It needs 1 more electron to become stable, therefore, it is highly reactive.
Compounds=Chemically combined, fixed proportions,and components change properties.
Both= Made of elements, and 2 or more components.
Mixtures=Physically combined, variable proportions, and components retain properties.
