IB DP Chemistry: HL复习笔记1.2.6 Real Gases
Real Gas Behaviour The ideal gas equation does not fit all measurements and observations taken at all conditions with real gases The relationship between pressure, volume and temperature shows sign...
IB DP Chemistry: HL复习笔记1.2.5 Gas Law Relationships
Gas Law Relationships Gases in a container exert a pressure as the gas molecules are constantly colliding with the walls of the container Gas particles exert a pressure by constantly colliding with...
IB DP Chemistry: HL复习笔记1.2.4 The Ideal Gas Equation
Ideal Gas Equation Kinetic theory of gases The kinetic theory of gases states that molecules in gases are constantly moving The theory makes the following assumptions: The gas molecules are moving ...
IB DP Chemistry: HL复习笔记1.2.3 Avogadro's Law & Molar Gas Volume
Avogadro's Law Volumes of gases In 1811 the Italian scientist Amedeo Avogadro developed a theory about the volume of gases Avogadro’s law (also called Avogadro’s hypothesis) enables the mole ratio ...
IB DP Chemistry: HL复习笔记1.2.2 Reaction Yields
Reaction Yields Percentage yield In a lot of reactions, not all reactants react to form products which can be due to several factors: Other reactions take place simultaneously The reaction does not...
IB DP Chemistry: HL复习笔记1.2.1 Reacting Masses
Reacting Masses & Limiting Reactants The number of moles of a substance can be found by using the following equation: It is important to be clear about the type of particle you are referring to...
IB DP Chemistry: HL复习笔记1.1.6 Empirical Formulae
Empirical & Molecular Formulae The molecular formula is the formula that shows the number and type of each atom in a molecule E.g. the molecular formula of ethanoic acid is C2H4O2 The empirical...
IB DP Chemistry: HL复习笔记1.1.5 Moles-Mass Problems
Moles, Particles & Masses Since atoms are so small, any sensible laboratory quantity of substance must contain a huge number of atoms Such numbers are not convenient to work with, so using mole...
IB DP Chemistry: HL复习笔记1.1.4 The Mole Concept
The Mole The Avogadro constant (NA or L) is the number of particles equivalent to the relative atomic mass or molecular mass of a substance in grams The Avogadro constant applies to atoms, molecule...
