Stoichiometry
Define mole ratio
conversion factor derived from the coefficients of a balanced chemical equation interpreted in terms of moles
What is Kinetic theory
all matter consists of small particles in constant motion
amount, volume, and temperature
Balance the equation:
K(s) + H20(l) > KOH(aq) + H2
2, 2, 2, 1
According to Guinness World Records, what's the best-selling book of all time?
The Bible
Chemical reactions can be described in terms of what quantities?
number of atoms, molecules, moles, mass, and volume
What conditions must exist for a liquid to boil?
particles through out the liquid must have enough energy to vaporize
Define partial pressure
contribution of each gas in a mixture makes to the total pressure.
How many Liters are there at STP, if I have 2 moles of O2(g)?
44.8L O2
What was the first animal to ever be cloned?
A sheep
Define Percent yield
ratio of the actual yield to theoretical yield expressed in a percent
Why does boiling point of a liquid vary with pressure?
boiling occurs when vapor pressure equals that of external pressure. if atmospheric pressure changes, boiling point will change.
How does an elastic collision affect gas particles?
energy is conserved allowing them to continuously bounce
Assuming STP, how many milliters of oxygen are needed to produce 20.4 mL SO3?
2SO2 + O2 > 2SO3
10.2 mL O2
What is Scotland's National animal?
Unicorn
What quantities are always conserved in chemical action?
mass and atoms
What's the difference between an ionic solid and an amorphous solid?
Ionic solids have an ordered internal structure, amorphous do not.
What is the combined gas law?
(P1 x V1)/T1 = (P2 x V2)/T2
What is the volume of gas at 2.00 atm and 200.0 K if its original volume was 300.0 L at 0.250 atm and 400.0 K.
18.8 L
What actor-comedian found fame on the TV show "Mork and Mindy?"
Robin Williams
How can you gauge the efficiency of a reaction carried out in a lab?
by calculating percent yield
What must happen for sublimation to occur?
Vapor pressure of the solid must exceed atmospheric pressure
What is the difference between a real gas and an ideal gas?
ideal gas obeys the assumptions of kinetic theory, a real gas deviates from this unless within a small range of conditions
How many moles of gas occupy 98 L at a pressure of 2.8 atmospheres and a temperature of 292 K?
11 moles of gas
Mr. Cook and Mr. Olsen met playing what sport?
