When salt is added to ice , it comes into contact with the thin layer of water on the surface of the melting ice. ... This salt water has a lower freezing point, so the temperature of the ice bath can get even colder, thus freezing the ice cream more quickly.
Mass of solute ( m₁ ) = 50 g
mass of solvent ( m₂ ) 250 g
p = m₁ / m₁ + m₂ * 100 %
p = 50 / 50 + 250
p = 50 / 300
p = 0.17 * 100
p = 17%
hope this helps!
The molecule expand to relieve steric strain before undergoing torsion to a non-planar structure in order to have several resonating structures.
<h3>What is a molecule?</h3>
It should be noted that a molecule simply mean the group of atoms that are bonded together that represents the smallest fundamental unit if the chemical compound.
It should be noted that structures containing fused benzene rings have extensive conjugation. Due to this, they can undergo resonance.
This is vital in decreasing the overall energy of the molecule and helps increase its stability. When there's a change in torsion angle to relieve the steric strain, the molecule won't be planar, hence, the energy will increase and the stability will reduce.
