Chemistry

1. When making a dilution, you...

Correct answer: C

Rationale: The correct answer is C: 'Decrease the concentration of a solution.' When making a dilution, you decrease the concentration of a solution by adding more solvent, not solute. Adding more solute to a concentrated solution would increase the concentration, not dilute it. Changing the temperature of the solution does not directly relate to dilution. Therefore, the only correct statement related to the process of making a dilution is that you decrease the concentration of the solution by adding more solvent, making option C the correct answer.

2. Which of the following is the main organ responsible for producing enzymes?

Correct answer: B

Rationale: Rationale: The pancreas is the main organ responsible for producing enzymes. Enzymes are proteins that act as biological catalysts to speed up chemical reactions in the body. The pancreas produces and releases digestive enzymes that help break down carbohydrates, proteins, and fats in the small intestine to aid in the digestion and absorption of nutrients. The liver also plays a role in producing bile, which helps in the digestion and absorption of fats, but the main organ responsible for producing enzymes is the pancreas. The stomach produces gastric juices that contain hydrochloric acid and pepsin, which help break down food, but it is not the main organ responsible for producing enzymes. The small intestine is where most of the digestion and absorption of nutrients occurs, but it does not produce the enzymes itself; instead, it receives enzymes from the pancreas and other organs.

3. Which of the following is a property of amphiprotic substances?

Correct answer: C

Rationale: Amphiprotic substances can donate or accept a proton, so they can act as both acids and bases. The other choices do not accurately describe amphiprotic substances.

4. How does the amplitude of a wave relate to its intensity or loudness?

Correct answer: B

Rationale: Higher amplitude corresponds to larger displacement from equilibrium and translates to higher intensity or perceived loudness in sound waves.

5. What is the general formula for an alkene?

Correct answer: B

Rationale: The general formula for an alkene is \(C_nH_{2n}\), indicating the presence of a double bond between carbon atoms.

6. What literary device is used in the line "The sea whispered secrets to the shore"?

Correct answer: B

Rationale: The sentence gives human qualities to the sea, like whispering, creating personification.
