Gas Laws
What is the relationship between pressure and volume? (what law?)
Indirect - (Boyle's Law)
What is a solute and solvent?
Solute- thing being dissolved
Solvent- things doing the dissolving
What is the pH of water after a neutralization reaction
7 - Neutral
What is the 2nd Law of thermodynammics?
Entropy --> Heat and energy moves from high energy to low energy
- Moves towards randomness and disorder
What are the tree types of compound bonding?
How do electrons behave in each type of bond?
Metallic- Flow of electrons
Covalent- Share of electrons
Ionic- Transfer of electrons
What happens to a marshmallow in the microwave and why? (what law?)
The mallow expands as the temperature rises.
(Charles' Law)
What happens to the concentration of a solution when volume increases?
What is the pOH when the pH is 4.3
pOH = 9.7
14 = pH + pOH
List all the phases of matter and their proper phase changes as heat is added:
solid - melting-> liquid -vaporization-> gas
Who is Ernest Rutherford and what did he discover?
Chemist who discovered the nucleus using a gold foil
A ballon sits in a car that reached 35ºC, it had an initial volume of 6.2L. Write a mathematical representation of the final volume if the starting temperature was 20ºC.
(6.2)/(293.15) = (P2)/(308.15)
or
P2= (6.2 x 308.15) / (293.15
What is the mathematical relationship between pH and Hydronium [H+] concentration?
Logarithmic
if ph goes from 5 --> 3
[H+] conc. goes up 100 times
What happens to potential energy, kinetic energy, and the strength of IMFs during a phase change as heat is continuously added
P.E. --> increase
K.E. --> constant
IMF --> weaker
List 2 ways ideal gases behave:
- mass is negligible
- No IMF interactions
- No energy is lost in collisions
Bromothymol Blue has a pH range of 6.5-8, goes from yellow to blue. Would this be a good indicator to see a pH change from 9-11?
What components affect heat energy (Q=)?
m = mass
c = specific heat capacity
∆T = changes in temperature
What conditions would cause a real gas to behave like an ideal gas?
High temperature and Low pressure
A student titrated 25 mL of HCl solution with 200 mL of a 0.5 M NaOH solution. What was the concentration of the HCl solution?
MV=MV
4 M HCl
What happens to the KE and temperature when heat is applied?
When heat heat is added KE and Temp increase
