Gases
Choose a team (you may not choose your own)
You now have as many points as that team
What is another name for the indirect method for calculating the enthalpy of a reaction?
Hess's law
Is chlorine diamagnetic or paramagnetic?
Paramagnetic
Why did boron make diamond conductive in Julian's research?
The pressure will be bigger by the same factor of a trillion
If I put a red hot iron knife inside a bucket of water to cool it and I find it lost 5000kJ of thermal energy... How much energy did the water gain? Will it reach the same temperature originally had?
the same 5000 kJ. It will not reach the knife's original temperature due to having a different (presumedly higher) specific heat.
What does positive or negative change in enthalpy mean?
Gaining or losing energy. Positive is endo, negative is exo
What are the quantum numbers of chloride ion?
n=3, l=1, ml=1, ms=-1/2
Who was Julian's peer leader when he took chem 1?
Carlos
If there is a lot of interaction between the gas molecules. Would you say this gas is real or ideal?
Real
Surprise: You actually get quantum chemistry. I'm sorry I really wanted to mention this:
Are protons elementary or composite particles?
Composite particles
Heat flows from _____ to _____
from hot to cold
How many electrons fit into a p subshell? What about a p orbital?
6 into the subshell. 2 per orbital
Choose a team (you may choose your own)
If that team isn't currently in first place, they get two turns next choose they answer a question. If the team is currently in first place, they lose that turn.
What is the difference between elastic and inelastic collisions?
Elastic collisions don't lose energy
What does positive or negative heat mean?
Gaining or losing thermal energy. Positive is endo, negative is exo
Choose a team (you may choose your own)
Everyone in that team must say a random number from 1 to 10 at the count of 3. If 2 or more people say the same number, they lose half of their points. If this doesn't happen, they win 400 points
What electromagnetic wave has the least energy? A microwave, a gamma ray, visible light or an UV ray?
A microwave
Name 3 people who dropped this class
Answers may vary (a lot this time)
How many moles are there in 90L of a gas at STP conditions?
4.02 mol
How much energy is needed to raise the temperature of 30L of water from 50C to 67c
2,133.8 kJ
What is the enthalpy of formation of hydrogen gas?
zero
Choices: Au, Ag, Cu, Pd, Pt, Rh, Ru, Nb, Mo, Cr
