Chemistry

1. What type of reaction is represented by the following equation: Fe2O3 (s) + 3H2 (g) -> 2Fe (s) + 3H2O (g)

Correct answer: D

Rationale: The given equation involves a transfer of electrons from iron oxide (Fe2O3) to hydrogen gas (H2), resulting in the formation of iron (Fe) and water (H2O). This transfer of electrons indicates a redox reaction, where oxidation and reduction occur simultaneously. In this case, iron is reduced from a higher oxidation state in Fe2O3 to a lower oxidation state in Fe, while hydrogen is oxidized from its elemental state in H2 to form water. Therefore, the correct answer is D: Redox reaction.

2. Which word is most closely associated with the adjective "ambiguous"?

Correct answer: B

Rationale: "Ambiguous" implies uncertainty or multiple interpretations, making "vague" its closest synonym.

3. The small intestine is where most of the chemical digestion and nutrient absorption occur. What is the finger-like projection in the small intestine that increases its surface area for absorption?

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' The finger-like projection in the small intestine that increases its surface area for absorption is primarily the villi and microvilli. Villi are small, finger-like projections that line the inner wall of the small intestine, while microvilli are even smaller projections on the surface of the villi. Both structures significantly increase the surface area of the small intestine, allowing for more efficient absorption of nutrients. Rugae, on the other hand, are folds in the stomach lining that help with expansion when the stomach is full. Therefore, the rugae are not directly related to the increased surface area for absorption in the small intestine, making options A and B incorrect choices. Overall, options A, B, and C are all related to the structure of the small intestine but serve different functions, so the most appropriate answer is D, 'All of the above.'

4. Which force opposes the relative motion between surfaces in contact?

Correct answer: b

Rationale: Friction is the force that opposes motion between surfaces in contact.

5. When an atom gains or loses electrons, it becomes a(n):

Correct answer: C

Rationale: Gaining or losing electrons alters the atom's electron count and charge, creating a positively or negatively charged ion.

6. What is the stage of mitosis during which the nuclear envelope reforms?

Correct answer: C

Rationale: Rationale: - Prophase is the stage of mitosis where the nuclear envelope breaks down, allowing the chromosomes to condense and become visible. - Metaphase is the stage where the chromosomes line up along the metaphase plate in the middle of the cell. - Telophase is the stage where the nuclear envelope reforms around the separated sister chromatids at opposite poles of the cell. - Cytokinesis is the final stage of cell division where the cytoplasm divides to form two daughter cells, but it is not directly related to the reformation of the nuclear envelope.
