ions both undergo hydrolysis in water, making their aqueous solutions acidic. Common Mistakes Observed in 2020 According to the MPM Examination Report , students often struggled with: Significant Figures:

: Understand trends in Group 2 and Group 17, particularly reactivity with water and oxygen. Common pitfalls include misidentifying the electronic configuration of transition metal ions (e.g., X2+cap X raised to the 2 plus power having 5 unpaired electrons).

The 2020 STPM Chemistry Semester 2 paper (Paper 962/2) is particularly valuable for several reasons: ions both undergo hydrolysis in water, making their

The 2020 paper is particularly significant because it marked a return to the standard written examination format after periods of uncertainty. It is widely regarded by teachers and lecturers as a paper that tested fundamental concepts deeply rather than requiring obscure trickery. Mastering this paper provides a solid foundation for the subsequent Semesters. Study Resources The 2020 STPM Chemistry Semester 2

: ΔHf(MgO) = Σ(atomization + IE + bond dissociation + EA) + U

So: -602 = (+148) + (+738) + (+1451) + (+249) + (-142) + (+844) + U

indicates a spontaneous reaction. For example, the reaction between Pb4+cap P b raised to the 4 plus power H2cap H sub 2 was analyzed for spontaneity based on its +1.69 V value.
