Helium is a nonmetal. There are several reasons for this, it is unable to donate electrons and It has an extremely low melting point.
The relative volumes of chloroform and water that should be used is 9:10
Concentration of solution in chloroform = 
( moles of chloroform )
Concentration of solution in water = 
( moles of water )
Dissociation constant at 
; 
Concentration of solution in chloroform / Concentration of solution in water
Meaning;
Since mole is present in chloroform and mole is present in water, Total mole of Caffeine present is 
Now, we substitute our given values into the equation
Therefore, the relative volumes of chloroform and water that should be used is 9:10

Answer:
<h2><em><u>MASS</u></em></h2>
Explanation:
Inertia increases as an object's <u>Mass</u> increases.
Answer:
The correct answer is;
5. They were packaged at a higher pressure on the ground, thus causing the gas inside the packages to expand in the sky where the jet is at a lower pressure.
Explanation:
According to Boyle's law, the pressure of a given mass of gas is inversely proportional to it volume at constant temperature
P₁·V₁ = P₂·V₂
At the factories, the peanuts are packaged at atmospheric conditions whereby P₁ = 1 atm, however, the pressure of the air in the atmosphere decreases with altitude as such the pressure in the airplane jet is about a fraction of hat on the ground by about a factor of 0.7.
Therefore P₂ = 0.7 atm and we have
V₂ = P₁·V₁/P₂ = 1 atm×V₁/0.7 atm = 1.43·V₁
The volume increases at high altitudes
