Unit 3 Flashcards
what are the three IMFs and their description
dipole to dipole is when the positive end of a polar molecule attracts the negative end of another polar molecules
London Dispersion Force is when electrons disperse around two different molecules , every single molecule has these
Hydrogen Bonding is when a Hydrogen atom in a molecule bonds to Nitrogen, Oxygen, or Flourine
What is the connection to boiling point and IMFS
The stronger the IMF the higher the boiling point
What is the connection to Surface Tension and IMFS
the stronger the IMF the stronger the surface tension
What is the connection to Vapor Pressure and IMFS
The stronger the IMF the lower the vapor pressure
What is the connection to solubility and miscibility and IMFS and define both terms
Polar molecules dissolve/mix easily while non polar do not
solubility is when a solid and a liquid come together and the dissolve and miscibility is two liquids coming together and mixing
What is the formula for moles in a dilution situation
Mc * Vc = Md * Vd
What is the energy level of X-ray and what happens when it is emmited onto an atom and what does it tell you ?
High energy, ejects electrons from atom to determine element
What is the energy level of Ultraviolet and what happens when it is emmited onto an atom and what does it tell you ?
Medium energy, breaks molecule bonds to indentify element
What is the energy level of visible light and what happens when it is emmited onto an atom and what does it tell you ?
Medium energy, absorbs light and releases it, the electrons go to a higher shell then back down as they get rid of the light to identify the element.
What is the energy level of infrared and what happens when it is emmited onto an atom and what does it tell you ?
low energy, molecular vibrations to determine the types of bonds within a molecule
What is the energy level of microwave and what happens when it is emmited onto an atom and what does it tell you ?
Low energy, molecule rotates to determine the location of hydrogen bonds
what is the relationship between A and C
if there is a higher concentration there is a higher level of absorption
through the relationship of absorbance, how does a longer path length affect absorbance
creates a higher absorbance
what makes molecules deviate from the ideal gas law>
High pressure and low temperature
