Chemistry

1. The ability of a substance to dissolve in another is called:

Correct answer: A

Rationale: Solubility refers to the extent to which one substance can dissolve in another to form a homogeneous solution.

2. What is the relationship between the speed of a wave, its frequency, and wavelength in a given medium?

Correct answer: a

Rationale: In a given medium, the speed of a wave equals the product of its frequency and wavelength.

3. 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.

4. What property of matter measures the amount of space occupied by an object?

Correct answer: d

Rationale: Volume measures the amount of space occupied by an object.

5. Which vitamin is known to play a vital role in immune function?

Correct answer: D

Rationale: The correct answer is Vitamin D. Vitamin D is known to play a vital role in immune function as it helps regulate the immune system's response to infections and reduces inflammation. It is involved in the production of antimicrobial peptides that help fight off pathogens. Vitamin A is important for vision and skin health, Vitamin B12 is essential for red blood cell formation and neurological function, and Vitamin E is an antioxidant that protects cells from damage. However, Vitamin D specifically stands out for its crucial role in supporting the immune system, making it the correct answer in this context.

6. Which of the following is the main organ responsible for filtering urine?

Correct answer: A

Rationale: Rationale: The kidneys are the main organs responsible for filtering urine. They play a crucial role in the urinary system by filtering waste products and excess substances from the blood to produce urine. The urine then travels from the kidneys to the bladder through the ureters, where it is stored until it is expelled from the body through the urethra. The bladder stores urine temporarily, while the ureters are tubes that transport urine from the kidneys to the bladder. The urethra is the tube through which urine is expelled from the body.
