Chemistry
1. What is the characteristic property of acids?
- A. Bitter taste
- B. Sour taste
- C. Slippery feel
- D. Sweet taste
Correct answer: b
Rationale: Acids typically have a sour taste. The other choices do not accurately describe the characteristic properties of acids.
2. Nuclear fusion powers the sun and other stars. What is the main obstacle to achieving controlled nuclear fusion on Earth for energy production?
- A. Lack of suitable materials to handle high temperatures and pressures.
- B. Limited availability of fusion fuels like deuterium and tritium.
- C. Difficulty in containing the plasma where fusion occurs.
- D. All of the above.
Correct answer: D
Rationale: The main obstacle to achieving controlled nuclear fusion on Earth for energy production involves a combination of factors. A) Lack of suitable materials to handle high temperatures and pressures is a significant challenge due to the extreme conditions required for fusion reactions. B) Limited availability of fusion fuels like deuterium and tritium can pose a constraint on the scalability and sustainability of fusion energy. C) Difficulty in containing the plasma where fusion occurs is another critical issue as plasma instabilities and heat losses can hinder the efficiency of fusion reactions. Therefore, all of the options (A, B, and C) contribute to the challenges in achieving controlled nuclear fusion for energy production on Earth.
3. A table top has dimensions of 75cm by 50cm. What is its perimeter if opposite sides are equal?
- A. 125cm
- B. 150cm
- C. 200cm
- D. 50cm
Correct answer: B
Rationale: Rationale: - Given that the table top has dimensions of 75cm by 50cm. - Since opposite sides are equal, the table top can be divided into two pairs of equal sides: 75cm and 50cm. - To find the perimeter, we add up all four sides: 75cm + 50cm + 75cm + 50cm = 250cm. - However, since opposite sides are equal, we only need to consider two sides: 75cm + 50cm = 125cm. - Therefore, the perimeter of the table top is 125cm + 125cm = 150cm. - Hence, the correct answer is B) 150cm.
4. Locate the heart within the human body cavities.
- A. Dorsal cavity
- B. Ventral cavity
- C. Thoracic cavity
- D. Abdominal cavity
Correct answer: C
Rationale: Rationale: The heart is located within the thoracic cavity, specifically in the mediastinum, which is the central compartment of the thoracic cavity. The thoracic cavity is part of the ventral cavity, which also includes the abdominal cavity. The dorsal cavity refers to the posterior side of the body and does not contain the heart. The heart is situated in the thoracic cavity between the lungs and above the diaphragm, making option C the correct choice.
5. The sentence "The audience was captivated by the speaker's compelling story" implies that the audience:
- A. Was bored and disinterested.
- B. Found the story confusing.
- C. Was completely absorbed and engaged.
- D. Disagreed with the speaker's message.
Correct answer: C
Rationale: "Captivated" suggests the audience was completely held by the speaker's story.
6. A nurse needs to dilute 2 milliliters of a concentrated medication with 8 milliliters of sterile water. What is the final concentration of the solution in percent?
- A. 16.67%
- B. 20%
- C. 25%
- D. 50%
Correct answer: B
Rationale: Calculate the total volume of the solution (2 ml + 8 ml = 10 ml). Then, divide the volume of the concentrated medication by the total volume and multiply by 100%: (2 ml / 10 ml) * 100% = 20%.
