Answer:
Because the kind of compounds that you try to determine using paper chromatography (organic compounds) are usually not soluble in water. Furthermore, water could react chemically with some of this compounds, because it's a very reactive molecule. You need organic solvents that are mostly inert.
Answer:
0.5455
Explanation:
The moles of benzene in the process stream in 1 sec = 450 moles
The moles of toluene in the process stream in 1 sec = 375 moles
So, according to definition of mole fraction:
Applying values as:
<u>Mole fraction of benzene in the process stream = 0.5455</u>
Answer:
The mass of PCl₃ is 332.3 g.
The molecules of PCl₃ is
Explanation:
Given that,
Mass of P₄ = 75.0 g
Mass of Cl₂ = 275 g
We know that,
The reaction is
We need to calculate the moles of P₄
Using formula of moles
Put the value into the formula
We need to calculate the moles of Cl₂
Using formula of moles
Put the value into the formula
We need to calculate the number of moles of
Moles in 1 P₄ = 0.61
So,
We need to calculate the mass of
Using formula of mass
Put the value into the formula
We need to calculate the molecules of
Using formula of molecules
Where, n = number of moles
N = avagadro number
Put the value into the formula
Hence, The mass of PCl₃ is 332.3 g.
The molecules of PCl₃ is
