Common Types of Exercises and How to Approach Them
Chemistry: A Contemporary Approach covers a broad spectrum of problems. Here’s a breakdown of typical exercise categories with strategies for answering them.
- Atomic Structure and Periodicity
Sample Exercise: Calculate the number of neutrons in an isotope of carbon-14.
Approach:
- Atomic number of carbon = 6
- Mass number of isotope = 14
- Neutrons = Mass number – Atomic number = 14 – 6 = 8
Answer: 8 neutrons
- Chemical Bonding and Molecular Geometry
Sample Exercise: Draw the Lewis structure for NH₃ and determine its molecular shape.
Approach:
- Count valence electrons: N (5), H (1 each, total 3)
- Distribute electrons to satisfy octets and satisfy the formal charges.
- Recognize the trigonal pyramidal shape based on lone pairs on nitrogen.
Answer: Trigonal pyramidal geometry with bond angles approximately 107°
- Stoichiometry and Chemical Calculations
Sample Exercise: How many grams of NaCl are needed to prepare 500 mL of a 0.1 M solution?
Approach:
- Molarity (M) = moles of solute / liters of solution
- Moles of NaCl = Molarity × Volume in liters = 0.1 mol/L × 0.5 L = 0.05 mol
- Mass = moles × molar mass (NaCl = 58.44 g/mol)
- Mass = 0.05 mol × 58.44 g/mol = 2.922 g
Answer: Approximately 2.92 grams of NaCl
- Thermodynamics and Equilibrium
Sample Exercise: Calculate ΔG° for the reaction at standard conditions if ΔH° = –200 kJ/mol and ΔS° = 300 J/mol·K.
Approach:
- Use the Gibbs free energy equation: ΔG° = ΔH° – TΔS°
- Convert ΔS° to kJ: 300 J/mol·K = 0.3 kJ/mol·K
- At 298 K: ΔG° = –200 kJ/mol – (298 K × 0.3 kJ/mol·K) = –200 – 89.4 = –289.4 kJ/mol
Answer: ΔG° ≈ –289.4 kJ/mol
