What is the Ideal Gas Law?
A law that tells the relationships between four variables: temperature, pressure, volume, and molar amount for a gaseous substance at a given set of conditions.

What is Dalton's Law on Partial Pressure?
A law that says the total pressure created by a mixture of gases is the sum of the partial pressures of the individual gases that are present.

300
What is Boyle's Law?
A law that says a volume of a fixed amount of gas is inversely proportional to the pressure applied to the gas is the temperature is constant.
300
What are gases always doing?
Moving around

Use Dalton's Law on Partial Pressure for the problem: A 423 mL sample of dry oxygen at STP is transferred to a container over water at 22° C and 738 mm Hg. What is the new volume of the oxygen?
484 mL O2
400
What is an Arrhenius Base?
A type of reaction that has bases dissolving into an aqueous solution to create hydroxide ions (OH-).
400
Do gases take up more or less space than the solids and liquids that form them?
More space
400
Use the Ideal Law to solve the problem: A 7.50 liter sealed jar at 18 °C contains 0.125 moles of oxygen and 0.125 moles of nitrogen gas. What is the pressure in the container?

500
What is Charles's Law?
A law that says that the volume of a fixed amount of gas is directly proportional to its Kelvin temperature if the pressure is constant.
500
Name two properties of gases.
They're constantly moving, they will easily compress, they expand to fit their containers, they take up more space than the solid and liquids that form them.
500
Use the Ideal Gas Law to solve the problem: A 4.0 liter container has two gases inside, neon and argon. It is known that at 18 °C, the total pressure of the combined gases is 0.850 atm. If it is known that there are 0.100 moles of neon in the container, how many moles of argon are in the container?
0.042 moles argon
500
