Solutions Distinguish between the terms solute, solvent, solution and concentration (g dm-3 and mol dm-3) Solute - This is the substance which has been dissolved. Solvent - The bulk substance in which the solute was dissolved Solution - This is made...
Mass and Gaseous Volume Relationships in Chemical Reactions Calculate theoretical yields from chemical equations A balanced equation establishes the connection between the mass (or moles) of a known substance to the mass (or moles) of an unknown substance. For...
Chemical Equations Deduce chemical equations when all the reactants and products are given Chemical formulas are shorthand representations of compounds. Chemical reactions are represented by equations using the chemical formulas and symbols of the substances involved...
Formulas Define the terms relative atomic mass (Ar) and relative molecular mass (Mr) Relative Atomic Mass (Ar) - The weighted mean of the masses of the naturally occurring isotopes, on a scale in which the mass of an atom of the carbon-12 isotope is 12 units...
The Mole Apply the mole concept to substances A mole is the name given to a certain quantity. It represents 6.02 x 1023 particles. This number is also known as Avogadro's constant, symbolised L. L = 6.02 x 1023 mol-1 To apply this concept to substances, we use it like...
