Analysis of the Exam Questions and Answers
In this section, we will analyze some of the key questions from the January 2016 exam and provide the corresponding answers, along with explanations where necessary.
Sample Questions and Answers
1. Question on Atomic Structure:
- What is the electron configuration of an oxygen atom?
- Answer: The electron configuration of an oxygen atom is 1s² 2s² 2p⁴.
Explanation: This configuration indicates that oxygen has 8 electrons, with 2 in the first shell and 6 in the second shell.
2. Question on Chemical Bonding:
- Which type of bond is formed between sodium and chlorine in sodium chloride?
- Answer: Ionic bond.
Explanation: Sodium donates an electron to chlorine, resulting in the formation of oppositely charged ions that attract each other.
3. Question on Stoichiometry:
- How many moles are present in 32 grams of oxygen gas (O₂)?
- Answer: 1 mole of O₂.
Explanation: The molar mass of O₂ is 32 g/mol, thus 32 grams of O₂ equals 1 mole.
4. Question on Thermochemistry:
- What is the enthalpy change for the reaction?
- Answer: The answer would depend on the specific reaction given in the exam.
Explanation: Students must understand how to calculate enthalpy change using Hess's Law or enthalpy tables.
5. Question on Acids and Bases:
- What is the pH of a solution with a hydrogen ion concentration of 1 x 10⁻⁷ M?
- Answer: pH 7.
Explanation: A concentration of 1 x 10⁻⁷ M corresponds to a neutral pH of 7.
