Types of Solids
True or False? An example of an ionic solid is table salt.
What are the weakest type of intermolecular forces that occur between all molecules?
London Dispersion Forces
When an ionic compound dissolves in water, it separates into these.
Spectroscopy is the study of how matter interacts with:
Electromagnetic Radiation (light)
Gases behave most ideally under which of the following conditions?
High temperature and low pressure
Which solid is arranged in a structured lattice?
Ionic Solid
What force occurs when a hydrogen atom is bonded to nitrogen, oxygen, or fluorine?
Hydrogen Bonding
When two aqueous solutions are mixed and a solid forms, the solid is called this.
Precipitate
True or Flase? High frequency=shorter waves and more energy. Low frequency=long waves and less energy.
True
What is the pressure (in atm) of 0.75 mol of gas in an 18.0 L container at 305 K?
1.03 atm
I have a high boiling point and held together by strong covalent bonds. What solid am I?
Network Covalent Solid
The strength of dipole-dipole interactions depends on this property of a molecule.
Polarity
This type of force is primarily responsible for the solubility of ionic compounds in polar solvents like water.
Ion-Dipole Forces
When a particle is struck with Mircowave radiation it causes the particle to:
Rotate
What is the pressure of 3.00 g of O₂ gas in a 5.0 L container at 25°C?
0.36 atm
I have a high melting point but I am not conductive. What solid am I?
Ionic Solid
What type of forces occur between polar molecules?
Dipole-Dipole and London Dispersion Forces
According to Le Chatelier’s Principle, increasing pressure will increase the solubility of gases in liquids because of this effect.
A shift to the side with fewer gas molecules
When a particle is struck with Infared radiation it causes the particle to:
Vibrate (strech or bend)
Which of the following changes would increase the pressure of a gas the most (assume ideal behavior)?
Doubling the moles and keeping volume and temperature constant
What are the two types of alloys in metallic solids?
Interistical and Substitutional alloys
This force is strongest when molecules have a large electron cloud.
When no more solute can dissolve in a solvent at a certain temperature, the solution is called this.
Saturated
The photoecletric effect is when light(or electromagnetic radiation):
Has a metal surface, casuing electrons to be ejected from the surface
Which of the following best explains why real gases deviate from ideal gas behavior at high pressures and low temperatures?
Intermolecular forces and particle volume become significant
