Review Flashcards
What is the Kinetic Molecular Theory of Gases?
- The gas particles are in random constant motion
- The distance between the particles is greater than the
size of the particles - The intermolecular interactions in between these
particles are negligible for calculations involving the
ideal gas laws - The collisions between these particles is elastic
What is the Ideal Gas Law?
PV = nRT
How are the partial pressures and the total pressure related?
The pressure of the individual gases that compose the gas when the sum is found that value is the total pressure of the gas.
What happens when one gas increases in pressure?
The other gases that compose the gas do not decrease in pressure as a result rather the total pressure changes.
What is the difference between the arrow and double arrow?
The double arrow is for equilibrium reactions where the reaction is not complete whereas the single headed arrow shows that the reaction is complete.
What are the 3 states of matter?
- ) Solid
- ) Liquid
- ) Gas
What are some of the properties of a gas?
- Unlike the solid and liquid the gas is compressible
- The density is lower
- The particles are always in random constant motion
What is the formula for pressure?
P = Force/Area
What is the limiting reagent?
It is the substance that is limiting the yield or product being made.
What is a yield?
The product being produced.
What is the excess reagent?
The substance in the reaction that is found in abundance.
Among the 3 balloons where the 1st and 2nd are at the same height and the 3rd is lower than both what are some of the assumptions?
- Sealed
- Ideal gas
- Same temperature
- Same volume
- Same total moles
Which balloon has a greater O2 composition?
Balloon #3 because it is lower in height due to having more weight from the oxygen which is 16g/mol.
Which balloon has the greatest yield?
Balloon #2 because the concentration of H2 is higher than #3 since the height is greater. Balloon #1 is not triggered by a flame thus the H2 and O2 do not mix.
What is the relationship of sound and flame?
Balloon #2 does not have enough oxygen thus it requires diffusion to complete the reaction once the flame is near which prolongs the reaction causing a flame for a longer period of time and sound than balloon #3.
