For the antimony trichloride system, we assume dilution only when calculating concentrations. By making this assumption, are we adding random or systematic error to our data? Explain the error in this assumption.

A) the enthralling of formation for pure element in its standard state is always positivehope this : )

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.

Visible light is located in the middle of the spectrum.
