1. Gas Characteristics & Pressure
This is the SI unit of pressure, named after a French mathematician and physicist.
What is the Pascal (Pa)?
This simple gas law states that when pressure increases, volume decreases at a constant temperature.
What is Boyle's Law?
In the Ideal Gas Equation (PV = nRT), this letter represents the molar gas constant.
What is R?
In an aqueous solution, water acts in this role while the dissolved substance is the solute.
What is the solvent?
This type of chemical reaction involves a substance combining with oxygen to form oxygen-containing compounds while emitting heat.
What is a combustion reaction?
Standard atmospheric pressure at sea level is equal to this many millimeters of mercury (mmHg) or torr.
What is 760?
This law states that the volume of a gas increases with temperature when pressure and moles are constant.
What is Charles's Law?
This is the value of molar volume for one mole of an ideal gas at Standard Temperature and Pressure (STP).
What is 22.4 L?
This unit of concentration is defined as moles of substance divided by the volume of solution in liters.
What is Molarity (M)?
According to solubility guidelines, most compounds containing this anion (NO3^-) have no important exceptions and are soluble.
What is nitrate (NO3^-)?
This laboratory instrument uses a column of mercury supported by atmospheric pressure to measure pressure.
What is a mercury barometer?
According to Charles's Law, temperature must always be measured in this scale for calculations.
What is Kelvin (K)?
Dalton's Law of Partial Pressures states that the total pressure of a gas mixture is equal to the sum of these.
What are the partial pressures of each individual gas?
This equation is used when calculating serial dilutions by changing the volume of a solution (c1v1 = c2v2).
What is the dilution equation?
In oxidation-reduction (redox) reactions, this acronym reminds us that Reduction Is Gain of electrons.
What is RIG?
This law describes how lighter gases pass through tiny pores or pinholes faster than heavier gases.
What is effusion?
According to Avogadro's Law, equal volumes of gases at the same temperature and pressure contain an equal number of these.
What are moles (or molecules)?
This term describes the reactant that is completely consumed first and controls how much product can be formed.
What is the limiting reactant?
Ionic compounds that completely dissociate into ions in water and conduct electricity strongly are called strong types of these.
What are electrolytes?
When assigning oxidation numbers, uncombined free elements (like Cu or Cl2) are automatically assigned this oxidation state.
What is zero (0)?
Kinetic-molecular theory states that at any given temperature, all gases share the same value for this type of energy.
What is average kinetic energy?
Avogadro's Law states that volume is directly proportional to this variable representing the amount of substance.
What is the number of moles?
This calculation compares the actual yield of a product to the theoretical yield, expressed as a percentage.
What is reaction yield (or percent yield)?
This specific laboratory glassware is used to prepare a solution of a precisely known concentration to a calibration mark.
What is a volumetric flask?
This rule states that the sum of the oxidation numbers for all atoms in a neutral compound must equal this number.
What is zero (0)?
