Chemistry

1. Which element has the same number of protons and neutrons?

Correct answer: D

Rationale: Helium (He) - He-4 has 2 protons and 2 neutrons, while the other options have differing numbers.

2. The term "unconditional" in the context of UBI signifies that

Correct answer: C

Rationale: The unconditional aspect of UBI refers to the lack of strings attached to its receipt, aligning with C.

3. Ms. Valencia prepares the process standards. Which of the following is NOT a process

Correct answer: D

Rationale: In this question, Ms. Valencia is tasked with preparing process standards, which are systematic procedures or steps followed to ensure quality care. Options A, B, and C all refer to specific processes that are essential in healthcare: timely assessment, obtaining informed consent, and assessing patient satisfaction. However, option D about providing patient education is more focused on an outcome (patient education) rather than a specific process standard. While patient education is important, the question is asking for a process standard, making option D the correct answer as it does not directly relate to a specific process standard.

4. Imaginary unit multiples are used to represent numbers that cannot be obtained on the number line. Which of the following is equivalent to 5i?

Correct answer: C

Rationale: Rationale: - The imaginary unit, denoted as "i," is defined as the square root of -1. - Therefore, 5i can be expressed as 5 times the square root of -1, which is equivalent to 5√-1. - Option A, -5, is a real number and not an imaginary unit multiple. - Option B, i^5, is equal to i because i raised to any power that is a multiple of 4 results in 1, and i^5 is equivalent to i. - Option D, 1/5i, is the reciprocal of 5i and not equivalent to 5i.

5. How does polarization affect the intensity of light passing through a polarizing filter?

Correct answer: B

Rationale: A polarizing filter only allows light waves with a specific polarization direction to pass through, reducing the intensity of waves with different orientations.

6. What are some potential applications of understanding atomic structure in modern technology?

Correct answer: D

Rationale: Understanding atomic structure is crucial in various technological advancements. Designing new materials with tailored properties requires knowledge of atomic structure to manipulate their characteristics. Developing advanced electronics and nanotechnology involves working at the atomic level to create smaller, faster, and more efficient devices. Improving nuclear energy production and safety also relies on understanding atomic structure to enhance reactor design and safety measures. Therefore, all of the options provided (A, B, and C) are potential applications of understanding atomic structure in modern technology.
