Chemistry

1. What is the law that states energy can neither be created nor destroyed?

Correct answer: B

Rationale: Law of Conservation of Energy. This law applies to both chemical and physical processes, including chemical reactions.

2. Which additional information would be MOST relevant to the passage's argument?

Correct answer: C

Rationale: Choice C aligns with the passage's theme by demonstrating how historical knowledge directly impacted a contemporary solution, further supporting the argument for history's value.

3. In an SN2 reaction, the rate of the reaction is affected by

Correct answer: D

Rationale: In an SN2 reaction, the rate of the reaction is affected by both the concentration of the nucleophile and the electrophile. This is because in an SN2 reaction, the nucleophile directly attacks the electrophilic center, leading to the formation of the product. A higher concentration of nucleophile increases the chances of successful collisions with the electrophile, thereby increasing the reaction rate. Similarly, a higher concentration of the electrophile provides more reaction sites for the nucleophile to attack, also increasing the rate of the reaction. Therefore, both the nucleophile and electrophile concentrations play crucial roles in determining the rate of an SN2 reaction.

4. What property of a substance refers to its ability to be drawn into thin wires without breaking?

Correct answer: c

Rationale: Ductility is the property that describes a substance's ability to be drawn into thin wires without breaking.

5. Where does cellular respiration, the process of converting chemical energy into ATP, take place in eukaryotic cells?

Correct answer: C

Rationale: Rationale: Cellular respiration, the process of converting chemical energy into ATP, takes place in the mitochondria of eukaryotic cells. The mitochondria are known as the powerhouse of the cell because they are responsible for generating most of the cell's ATP through the process of cellular respiration. This process involves the breakdown of glucose and other organic molecules to produce ATP, which is the primary energy currency of the cell. The other organelles listed in the options (nucleus, ribosomes, and Golgi apparatus) do not play a direct role in cellular respiration.

6. What is the correct way to punctuate the following sentence: "She asked me if I wanted to go to the movies with her"?

Correct answer: D

Rationale: Option D uses a question mark within the quoted material as it is a direct question.
