Gas & Pressure
STP
Standard Temperature 0 C and Pressure 1 atm
The law that relates the temperature and pressure of a gas to each other
Gay Lussac's Law
PV= nRT
Ideal gas law
Used in explosives
Nitric acid
Strong acid is a strong___________
electrolyte
At sea level, the average height of mercury in a barometer is
760 mm Hg
The volume of a fixed mass of gas varies inversely with the pressure at constant temperature.
Boyle's Law
According to Graham’s Law, the rate of effusion of gas A divided by the rate of effusion of gas B under the same conditions is equal to
√Molar mass of B/ √Molar Mass of A
Used as fertilizers
Phosphoric acid and Sulfuric acid
ionizes / dissociates partially/slightly in solution
Weak acid or base
Force over unit area
Pressure
The total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases.
Dalton's Law of Partial Pressures
The rates of effusion of gases at the same temperature and pressure are inversely proportional to their molar masses.
Graham's Law of Effusion
An acid that contains only two different elements: hydrogen and one of the more electronegative elements.
Binary Acid
ionizes/dissociates completely in aqueous solution.
Strong Acid/ Strong Base
SI unit of Pressure
Pascal Pa
The relationship between pressure, volume, and temperature is expressed by this law
Combined Gas Law
Pressure times volume equals molar amount times 0.0821 Latm/(molK) times temperature in kelvins.
Ideal Gas Law
An acid that is a compound of hydrogen, oxygen, and a third element, usually a nonmetal
Oxyacid
A substance that increases the concentration of hydroxide ions, OH-, in aqueous solution.
Arrhenius Base
convert 920 mmHg to atm
1 atm = 760 mm Hg
x = 920 mmHg
920/760 = 1.21 atm
The volume of a fixed mass of gas varies directly with the kelvin temperature at constant pressure.
Charle's Law
Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
Avogadro's Law
H2SO4
Sulfuric Acid
A chemical compound that increases the concentration of hydrogen ions, H+, in aqueous solution.
Arrhenius Acid
