What is an Ideal Gas?
A gas which has molecules that occupy negligible space with no interactions between them.
What is the ideal gas equation?
pV = nRT.
How is Percentage Yield calculated?
Percentage yield = (Actual yield / Theoretical yield) × 100.
What is Stoichiometry?
The relative quantities of substances in a reaction.
What is Water of Crystallisation?
Water molecules that form part of the crystalline structure of a compound.
What does ‘anhydrous’ mean?
A crystalline compound containing no water.
What does a high atom economy indicate?
A process is more sustainable as there is less waste produced.
How is percentage atom economy calculated?
Percentage atom economy = (Molecular mass of desired product / Sum of molecular masses of all reactants) × 100.
What is the Avogadro Constant (Ng)?
The number of particles per mole of substance (6.02 × 10^23 mol^-1).
What is an empirical formula?
The simplest whole number ratio of atoms of each element present in a compound.
What does ‘hydrated’ mean?
