Study Notes
Equilibrium and Potential Energy
- Stable equilibrium occurs when U is minimum.
- At stable equilibrium, d²U/dx² > 0.
- For a particle moving along the x-axis, the potential energy is given by U = (1/3)x³ - 9x² + 20x.
Force and Momentum
- The force exerted by a light beam on a surface is given by F = I / c, where I is the intensity of the wave and c is the speed of light.
- The rate of change of momentum of photons is given by dP/dt = F.
Chemistry
- The reaction between I⁻, ClO₃⁻, and H₂SO₄ yields Cl⁻, HSO₄⁻, and I₂.
- Stoichiometric coefficient of HSO₄⁻ is 6 in the balanced equation.
- Iodide is oxidized in the reaction.
- Sulphur is reduced in the reaction.
- H₂O is one of the products in the reaction.
- Anthraquinone can be produced through EAS, oxidation, and Diel's Alder reaction.
Carbonyl Compounds
- Carbonyl compounds undergo reversible hydration in aqueous solution.
- The equilibrium is shifted towards the product at 25°C for certain carbonyl compounds.
Basic Strength
- The basic strength of different amines depends on their molecular structure.
- The correct order of basic strength varies depending on the specific amines being compared.
