Tribhuvan University — Basic Chemistry I (CHE-101) | past year question 2082

Group A — Inorganic covers wave functions, hybridization, radial distribution functions, fission/fusion, ionization potential, electronegativity, zinc blende structure, VSEPR, HSAB, volumetric analysis, and the Born-Haber cycle. Group B — Organic covers free radical vs. electrophilic addition (peroxide effect), SN1 vs. SN2, intermolecular forces, potential energy diagrams, Newman projections of n-butane, R/S configuration, racemic mixtures vs. meso compounds, carbocation stability, boiling points, Zaitsev's rule, and propyne hydration. Group C — Physical covers Van der Waals equation with the RMS velocity calculation (≈ 779 m/s), Kirchhoff's equation, isothermal expansion (ΔU = ΔH = 0 for ideal gas), mean free path, surface tension by drop weight, crystal types, PCl₅ equilibrium (Kc ≈ 0.188 mol/L at 1L), buffer solutions (pH = pKa + log ratio), Raoult's law, half-life of 2nd order reactions, Arrhenius equation (T ≈ 316 K), and bond enthalpy calculation (ΔH = −125 kJ/mol).

Specification Grids of All Subject Class-10

Subject specification grids, also known as subject matrices or subject frameworks, are invaluable tools that help organize and structure the curriculum in educational institutions. These grids provide a clear outline of the subjects or disciplines offered, along with the corresponding learning objectives, content, and skills to be covered. The importance of subject specification grids cannot be overstated, as they serve several key purposes in the educational context. First and foremost, subject specification grids promote curriculum coherence and consistency. By clearly defining the scope and sequence of each subject, these grids ensure that all teachers and educators are on the same page regarding what needs to be taught and learned. This consistency across different classrooms and instructors facilitates a smoother educational experience for students, as they encounter consistent expectations and content regardless of the teacher they have or the classroom they are in.

Atomic Habits: Building Blocks of Lasting Change

A study companion for James Clear's Atomic Habits — exploring the science of small changes and how they compound into remarkable results. Use this notebook to capture key insights, discuss core concepts like habit loops, identity-based change, and the 1% rule, and inspire each other to take action. Every big transformation starts with one tiny habit — let's study how.
