Mole concept & limiting reagents
Count reacting particles before comparing masses.
Read & practise →Chemical bonding: shape, polarity & orbitals
Separate electron arrangement, molecular shape and the net dipole.
Read & practise →Equilibrium, weak acids & buffers
Write the equilibrium relation before choosing an approximation.
Read & practise →Electrochemistry: from reaction to cell potential
Balance the electron transfer, then build the reaction quotient.
Read & practise →Coordination chemistry: read the formula carefully
Count charge, donor atoms and particles as three separate questions.
Read & practise →Organic fundamentals: explain the reaction
Use electron movement and stability to organise what you remember.
