Chemistry Review: Units 5-9, Thermochemistry, and Lab Fundamentals

A comprehensive set of practice questions covering molecular geometry, intermolecular forces, thermochemistry, stoichiometry, and acid-base equilibrium based on the lecture notes.

How can you rank the strength of intermolecular forces (IMFs) for different substances?

By visually evaluating the substances or by comparing their molar mass and polarity.

What characterizes the properties of hydrates and polyatomic ions in nomenclature?

Naming procedures specifically developed for Naming Hydrates and Polyatomic Ions.

What calculation is used to determine the composition of a compound or hydrate by mass?

Calculating the percent composition and empirical formula.

What concept explains why certain substances dissolve in one another based on polarity?

"Like Dissolves Like" (Polarity and Electronegativity).

What theory is used to describe the properties of phases and the behavior of particles?

Kinetic Molecular Theory (KMT).

In a heating curve, what distinguishes an endothermic phase change from an exothermic one?

Endothermic changes absorb energy, while exothermic changes release energy.

What specific points can be identified on a Phase Diagram?

Normal melting and boiling points.

Which components are required for specific heat and heating curve calculations?

Molar heat of fusion, molar heat of vaporization, and the specific heat equation.

What temperature conversion is specifically required in Unit 7?

Converting Celsius ($^\circ C$) to Kelvin ($K$).

How is viscosity of liquids affected by environmental conditions?

Viscosity changes with temperature changes.

What is the study of dosage and substance toxicity covered in Unit 8?

$LD_{50}$ calculations.

What are the two common acronyms for the diatomic elements according to the notes?

BrINCIHOF or HONCIBRIF.

Which charts are essential for identifying reaction possibilities and product states?

What principle explains how a system at equilibrium responds to stress?

Le Chatelier's Principle and Shifting Equilibrium.

What is the mathematical expression for the equilibrium constant of a reaction?

$K_{eq}$ Equilibrium Law Expressions.

What constant is used for the auto-ionization of water calculations?

$K_w$.

Which four measures are calculated to determine the acidity or basicity of a solution?

$[H_3O^+]$, $[OH^-]$, pH, and pOH.

What laboratory technique is used to determine the concentration of an unknown acid or base?

Titration.

What are the three main types of chemical equations identified in Unit 8?

Word equations, balanced equations, and net ionic reactions.

What concept includes molarity and the process of decreasing concentration?

Molarity and dilutions.
