Gas Laws
The volume of a given mass of a gas is inversely proportional to it's pressure at a constant temperature
What is Boyle's Law
Under the same conditions of temperature and pressure, the rate of diffusion of a gas is inversely proportional to the square root of its density.
What is Graham's Law?
The mass in grams of one mole of substance.
What is molar mass?
The amount of solute contained in a given volume of the solution.
What is the concentration of a solution?
An apparatus used in volumetric analysis which is designed to deliver a definite volume.
What is a pipette?
The volume of a given mass of a gas is directly proportional to its absolute temperature at constant pressure.
What is Charles' Law?
Distance over Time.
What is a Rate?
True or False: The molecular mass is not always a multiple of the empirical mass formula.
The apparatus used to prepare molar solutions.
What are volumetric flasks and measuring cylinders?
The point at which the reaction is complete
What is end point?
Standard Temperature and Pressure.
What are 273 K and 760 mm Hg?
The relationship between molecular mass of a gas and its density.
What is directly proportional?
The number of atoms in one Relative atomic mass unit in grams of any element.
What is Avogadros Number?
True or False: During dilution, the amount of solute changes as the volume of the solution increases.
What is False?
An indicator used to detect weak acid and strong base.
What is Phenolpthaleain?
The relationship between volume, pressure, and temperature of a fixed mass of gas can be given by the expression which combines both Charles' and Boyle's Laws.
What is the Combined Gas Law or Ideal Gas Equation?
The process by which particles spread out from a region of high concentration to a region of low concentration.
What is diffusion?
Mass of an element in grams divided by molar mass.
What is number of moles of a substance?
A chemical equation in which the reactants and products are in whole number ratios.
What is a stoichiometric equation?
The process by which an unknown concentration of a solution is determined by use of a standard solution in a titration experiment.
What is standardization?
The result of collisions between the gas particles and the walls of the container.
Pressure
True or False: Gases with a low density diffuse faster than those with high densities.
What is True?
The sum of all relative atomic masses of the atoms in a molecule or compound
What is the relative molecular mass?
Ions which do not undergo change in a chemical reaction and are omitted when writing the ionic equation.
What are spectator ions?
A titration used to standardize solutions and to determine the purity of compounds.
What is a redox titration?
