TBR General Chemistry *II* Exam Questions & Answers 2024 *Solubility* - ANSWER-*TBR Gen Chem Ch. VII* Solubility equations - ANSWER- Solubility definition The ability of a solid to dissolve into a solvent to form a solution. The breaking apart of a lattice to allow particles to move freely in the solvent. - ANSWER-When a salt dissociates into water, ionic forces holding the charged species together break and interactions with the dipoles of water form. Salts dissociate from the su...

Electron configuration for cations - Answer-Subtract 1 from exponent of highest n-value orbital (ex. remove from 4s before 3d) Ag+ = [Kr]5s^1 4d^9 Electron configuration for anions - Answer-Add 1 to closest orbital Cl- = [Ne]3s^2 3p^6 Atomic orbitals - Answer-s, p, d, f Primary vs secondary structures of proteins - Answer-Primary - AA chain (linked by peptide bonds) Secondary - stabilized by non-covalent bonds (alpha helices & beta sheets) Most bonds in organic compounds are - Answer-cov...

Chemistry definition correct answers Study of structure, properties, transformations of matter Matter correct answers Anything that has mass + takes up space Phases: solid, liquid, gas Condensed phases = solids + liquids Intermolecular Forces (IMF) correct answers = Interactions between molecules/atoms/ions Solution correct answers = Homogenous mixtures of 2+ pure substances In a solution, the solute is dispersed uniformly throughout the solvent - Solute = compound(s) in lesser amount - ...
