Chemistry
1. 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.
2. What is the functional group present in esters?
- A. Hydroxyl
- B. Carbonyl
- C. Ester
- D. Amine
Correct answer: C
Rationale: Esters have the functional group -COO-, representing a carbonyl group bonded to an oxygen atom. The other choices are associated with different functional groups.
3. As a young manager, she knows that conflict occurs in any organization. Which of the
- A. Can be destructive if the level is too high
- B. Is not beneficial; hence it should be prevented at all times
- C. May result in poor performance
- D.
Correct answer: C
Rationale: Conflict in an organization is a natural occurrence that can either be constructive or destructive. Option C is the correct answer because conflict may indeed lead to poor performance if not managed effectively. When conflict is left unresolved or unaddressed, it can create tension, decrease morale, and hinder productivity. By recognizing that conflict can impact performance, the young manager can take proactive steps to address and resolve conflicts in a constructive manner to minimize its negative effects and promote a healthy work environment.
4. The fluid-filled, jelly-like substance within the cell that suspends the organelles is called the:
- A. Nucleus
- B. Cytoplasm
- C. Plasma membrane
- D. Golgi apparatus
Correct answer: B
Rationale: The correct answer is B: Cytoplasm. Cytoplasm is the fluid-filled, jelly-like substance within the cell that suspends the organelles. It is where many cellular processes take place, such as metabolism and protein synthesis. The nucleus (option A) is the organelle that contains the cell's genetic material, the plasma membrane (option C) is the outer boundary of the cell that regulates what enters and exits the cell, and the Golgi apparatus (option D) is involved in processing and packaging proteins. Understanding the functions of each organelle is crucial in recognizing that the cytoplasm is the correct answer in this context.
5. What literary device is used in the line "The sea whispered secrets to the shore"?
- A. Alliteration
- B. Personification
- C. Onomatopoeia
- D. Hyperbole
Correct answer: B
Rationale: The sentence gives human qualities to the sea, like whispering, creating personification.
6. What is the main reason why elements in Group 18 (Noble gases) are generally unreactive?
- A. They have high atomic masses
- B. They lack valence electrons
- C. Their outermost electron shells are completely filled
- D. They exist as single atoms, not molecules
Correct answer: C
Rationale: Noble gases have their outermost electron shells filled with 8 electrons, achieving a stable configuration with minimal urge to gain or lose electrons, making them less prone to chemical reactions.
