CH2Cl2 is more soluble in water because it is polar and CCl4 is not soluble in water because it is non-polar .
<h3>What is polar solvent ?</h3>
It is a type of solvent which have large dipole moments . it possess charge separation . it has the ability to dissolve polar materials .
They have bond between atoms with different negativities .
example ; H2O is a polar solvent . and CH2Cl2 is also polar .
<h3>What is non-polar solvent ?</h3>
It is a type of solvent which are composed of atoms that have similar electronegativity .
they lacks partial charge .
example ; benzene ,hexane ,and CCl4 is non - polar solvent .

#SPJ4
Answer:
Pressure of neon = 1.17 atm
Pressure of hydrogen = 0.63 atm
Explanation:
Given data:
Number of moles of H₂ = 2.5 mol
Number of moles of Ne = 4.6 mol
Total pressure = 1400 mmHg (1400/760 = 1.8 atm)
Solution:
We will solve this problem through mole fraction method.
Total number of moles = 2.5 + 4.6 = 7.1
Mole fraction of H₂ Mole fraction of Ne
2.5 mol/7.1 mol= 0.35 4.6mol/7.1mol = 0.65
Pressure of hydrogen = 0.35 × 1.8 atm
Pressure of hydrogen = 0.63 atm
Pressure of neon = 0.65 × 1.8 atm
Pressure of neon = 1.17 atm
Total pressure which is already given is sum of partial pressure of hydrogen and neon gas.
0.63 atm + 1.17 atm = 1.8 atm
Answer:
%Sgr = 1% (1 sig.fig.)
Explanation:
mass water = 350ml x 0.975g/ml = 341.25g
mass sugar added = 4g
solution mass = 341.25g + 4g = 345.25g
%sugar = (4g/345.25g)·100% = 1.1586% ≅ 1% (1 sig.fig)
