Chapter 10 - Gases Flashcards
-Convert between pressure units with an emphasis on torr and atmospheres -Calculate P, V, n, or T using the ideal gas equation -Understand how the gas laws relate to the ideal gas equation & apply the gas laws in calculations -Calculate the density or molecular weight of a gas -Calculate the volume of gas used or formed in a chemical reaction -Calculate the total pressure of a gas mixture given its partial pressures or information for calculating partial pressures -Describe the kinetic mol
10.1
Even though different gaseous substances may have very different _____ properties, they behave quite similarly as far as their ____ properties are concerned.
Chemical, physical
10.1
These gases exist as gases under ordinary conditions of temperature & pressure
Noble gases (monatomic)
H2, N2, O2, F2, Cl2 (diatomic)
10.1
Gases expand spontaneously to fill their ____. Because of this, the volume of a gas equals _____. Gases are ___ compressible: when pressure is applied to a gas, its volume _____.
Containers.
The volume of its container.
Highly.
Readily decreases.
10.1
Gases form ___ mixtures with other gases.
Homogeneous
10.1
The characteristic properties of gases arise because _____.
The individual molecules are relatively far apart, so each molecule behaves as if it were alone, so different gases behave similarly, even though they’re made up of different molecules.
10.1 - Give It Some Thought (p. 395)
What’s the major reason that physical properties don’t differ much from one gaseous substance to the next?
The molecules are far apart, so they act as if they’re alone (independently from the other molecules).
