First modules
How many electrons fit inside a p subshell?
6
If two atoms with very similar electronegativities form a bond, will it be non-polar, weakly polar, or strongly polar?
Weakly polar
How can we tell if an element is reduced or oxidized in a reaction?
We check the elements' oxidation numbers to see if they lost or gained electrons. Oxidations Is Losing. Reduction Is Gaining.
Explain how you would find the frequency of an electromagnetic wave knowing only its wavelength in nanometers.
Convert it to meters and divide the speed of light by it.
How many quizzes were there? (not counting today's google forms)
13
(on your board) wtite the expression for an atom with 35 protons, 36 electrons, and 48 neutrons
8335Br-
What is the molecular geometry of xenon tetrafluoride?
Square planar
How do we calculate the mole percentage of an element in a compound?
Moles of that element / total moles times 100
What are STP conditions?
Temperature = 0 Celcius (273 Kelvin)
Pressure = 1 atm
What were the names for the original 4 teams?
Bills Group, Team Gold, Team Star and Team Tritium
If that team shoots down the cups in their first try, they gain 400 points. If not, you gain them.
What is the oxidation state of Chlorine in perchlorate ion?
+7
Atomic radius, electronegativity, ionization energy, and electron affinity
True or false:
Ideal gases lose a lot of energy to friction
False
What is Julian's position in the chem 1305 peer leaders council?
Social media manager
How many valence electrons does nitrogen have? What about nitride ion?
Nitrogen has 5, nitride has 8
What is the correct formula of nitric acid?
HNO3
In aqueous chemistry, if an ion forms part of the precipitate formed, will it be in the net ionic equation or not? Is it a spectator ion?
It's not a spectator ion, so it appears in the net ionic equation
How much energy do you need to raise the temperature of 1 milliliter of water by 2 celcius?
Q = 8.368 Joules
What is Jesus' favorite exploration?
Butane bubbles
How many moles are there in 2 kilograms of vanadium metal?
39.26 moles
In a lewis structure, an oxygen atom has 1 single bond and 3 lone pairs around it. What's its formal charge?
-1
Choose a team
Next turn, that team can change their choice after seeing what question they get. The other team gains 500 points.
If I have 50 moles of xenon and 30 moles of neon in the same container, what is the molar fraction of xenon?
0.625 (or 5/8 or 50/80)
What peer leader has office hours at the same time as Julian?
Marcy
