Ideal Gas Law
What is the formula for the Ideal Gas Law?
PV=nRT
Name three intermolecular forces
London Dispersion forces, dipole-dipole forces and hydrogen bonds
What is a solution?
A homogenous mixture of two or more substances
What is the range of the electromagnetic spectrum?
Radio waves to gamma rays
How would a Maxwell-Boltzmann graph change if heat was added to a gas?
The peak would occur further to the right but lower
If the pressure of a gas is doubled while the volume remains constant, what happens to the temperature?
Temperature doubles
Which type of intermolecular is the strongest?
Hydrogen bonds
What is the difference between a solute and a solvent?
A solute is the substance being dissolved and the solvent is doing the dissolving
What is the range of wavelengths of visible light?
400nm to 700nm
Why do covalent network solids have a higher boiling point than molecular solids?
They have covalent bonds in every direction that are harder to break
If 4 moles of gas at 300K occupy a volume of 10L, what is the pressure?
12.1 atm
How do intermolecular forces affect boiling points?
Stronger intermolecular forces lead to higher boiling points.
What is the effect of temperature on solubility?
Increased temperature increases solubility
Higher frequency corresponds to higher energy
Why would you use thin layer chromatography?
To separate substances not visible to the naked eye
How does the Ideal Gas Law apply to real gasses at high pressure?
Real gasses deviate from the Ideal Gas Law due to intermolecular forces
Give an example of a substance with strong dipole-dipole interactions.
HCl, H2O, etc
What would be the effect on molarity if you add more water to a 2M solution?
A substance reflects light at 510nm. What color is it?
Green
Which state of matter can be compressed and why?
Gas because there is so much space between each of the particles
What are the units included in the constant R in the Ideal Gas Law?
Units for pressure, volume, temperature and number of moles
Explain how molecular size affects London Dispersion Forces.
Larger molecules have greater surface area, leading to stronger London dispersion forces.
What is the molarity of a solution with 100g LiO in 100mL of water?
40M
What is the relationship between wavelength and energy?
Shorter wavelengths have higher energy
How many grams of NaCl would you need to make 500mL of a 3M solution?
87 grams NaCl
