1. What is the common name for the compound CH₃COOH?

• A. Acetic acid
• B. Formic acid
• C. Butyric acid
• D. Propionic acid

Correct answer: A

Rationale: CH₃COOH is commonly known as acetic acid. The other choices represent different organic acids.

2. Which statement correctly describes the concept of ionization energy?

• A. The energy required to remove an electron from an outermost shell.
• B. The energy released when an electron bonds with an atom.
• C. The total energy possessed by all electrons in an atom.
• D. The energy needed to change an atom's nucleus.

Correct answer: A

Rationale: The energy required to remove an electron from an outermost shell. Ionization energy varies depending on the element and electron configuration, indicating its difficulty to lose electrons and influencing its reactivity.

3. What is the primary factor that determines whether a solute will dissolve in a solvent?

• A. Temperature
• B. Pressure
• C. Molecular structure
• D. Particle size

Correct answer: c

Rationale: The molecular structure of the solute and solvent plays a key role in determining solubility. The other choices may influence solubility but are not the primary determining factor.

4. Which of the following is the smallest unit of matter?

• A. Molecule
• B. Atom
• C. Compound
• D. Element

Correct answer: B

Rationale: An atom is the fundamental building block of matter, while molecules are formed by the combination of atoms.

5. He emphasizes to the team that they need to put their efforts together towards the attainment

• A. Span of control
• B. Unity of direction
• C. Unity of command
• D. Command responsibility

Correct answer: B

Rationale: The correct answer is B: Unity of direction. Unity of direction is a principle of management which states that all activities within an organization should be directed towards the same objectives. In this scenario, the leader is stressing the importance of aligning the team's efforts towards a common goal or objective. This ensures that everyone is working towards a shared purpose, avoiding conflicting or contradictory actions. Span of control refers to the number of subordinates a manager can effectively supervise. Unity of command relates to the principle that employees should receive orders from only one supervisor to avoid confusion and conflict. Command responsibility is a term often used in the context of accountability for actions taken under one's command. Therefore, the most appropriate concept in this context is Unity of direction.

6. A study finds a correlation between increased ice cream consumption and lower crime rates. What is the MOST likely explanation for this observation?

• A. Ice cream directly reduces criminal behavior.
• B. People who commit crimes eat less ice cream.
• C. A third factor, like hot weather, influences both.
• D. The study design is flawed and the connection is false.

Correct answer: C

Rationale: The most likely explanation for the correlation between increased ice cream consumption and lower crime rates is a third factor influencing both variables. In this case, hot weather could be the common factor as both ice cream consumption and crime rates tend to increase during warmer months. This scenario illustrates the importance of considering confounding variables when interpreting correlations.
