DAILY DOUBLE! pressure varies inversely with volume (temp is constant)
What is Boyle's Law
A sample of oxygen gas collected in the lab occupies a volume of 250. mL when its pressure is 720. mmHg. What volume will the gas occupy at a pressure of 760. mmHg if the temperature is held constant?
What is 237 mL
A sample of neon gas occupies a volume of 742 mL at 35˚C. What volume will the gas occupy at 60˚C if the pressure is held constant?
What is 802 mL
DAILY DOUBLE! Conditions where gases act the most ideal
What is low pressure and high temperature
when measured at the same temp and pressure, volume of gases reactants and products of chemical reactions are always in simple ratios of whole numbers
What is Gay-Lussac's Law of combining volumes
A 8.3 L gas sample at standard pressure is compressed to a volume of 2.8 L and the temperature is increased from 30˚C to 65˚C. What is the new pressure of the gas in atms?
What is 3.3 atm
DAILY DOUBLE! A gas’s pressure doubles while its Kelvin temperature is halved. How does its volume change
What is the volume stays the same
combination of the gas laws
What is the Combined Gas Law
DAILY DOUBLE! When hydrogen gas is collected over water at 30˚C, (water vapor pressure 31.8 mmHg) the partial pressure of the hydrogen gas was determined to be 732.8 mmHg. What was the barometric pressure at the time the gas was collected? (the barometric pressure equals the sum of the partial pressures)
What is 765 mmHg
DAILY DOUBLE! The R stands for what in the Ideal Gas Law. (name, value, and units)
What is the Ideal Gas Constant: 8.314 kPa*L*K-1*mol-1
