1. The van't Hoff factor (i) accounts for the number of particles a solute dissociates into in solution. For a compound that dissociates completely in water, i would be...

• A. 0
• B. Less than 1
• C. 1
• D. More than 1

Correct answer: D

Rationale: The van't Hoff factor (i) represents the number of particles a solute dissociates into in solution. For a compound that dissociates completely in water, i would be more than 1 because it breaks apart into more particles than the original compound. This is due to complete dissociation leading to an increase in the number of particles in solution, resulting in i being greater than 1. Choice A is incorrect as a compound that dissociates completely will not have an i value of 0. Choice B is incorrect because when a compound dissociates completely, the van't Hoff factor is not less than 1. Choice C is incorrect as a compound that dissociates completely will not have an i value of 1, but rather more than 1 due to the increased number of particles in solution.

2. If the price of a shirt was originally $30 and it is now being sold at a 20% discount, what is the sale price of the shirt?

• A. $24
• B. $25
• C. $26
• D. $28

Correct answer: A

Rationale: To find the discount amount, calculate 20% of $30: 0.20 × $30 = $6. Subtract the discount from the original price to get the sale price: $30 - $6 = $24. Therefore, the correct answer is $24. Choices B, C, and D are incorrect as they do not reflect the correct calculation of applying a 20% discount to the original price of $30.

3. Which of the following statements is an opinion?

• A. Despite the progression of the Internet, printed media was still very popular in the forms of both fiction and non-fiction books
• B. Although some people may say that the act of reading is not complete without turning a page, sliding a finger across the screen, or pressing a button to read more onto the next page is just as satisfying to the reader
• C. With the invention of the Internet, reliance on books for information quickly changed
• D. Stories have been a part of the world since the beginning of recorded time

Correct answer: B

Rationale: Statement B is an opinion because it expresses a personal viewpoint about the act of reading and satisfaction related to different reading formats. The phrase 'just as satisfying to the reader' reflects subjective feelings and preferences rather than objective facts. Choices A, C, and D are not opinions but statements of fact. Choice A discusses the continued popularity of printed media despite the Internet's advancement. Choice C talks about the change in reliance on books due to the Internet. Choice D states the historical presence of stories in the world, which is a factual statement about the past.

4. Which of the following is NOT a common symptom of pregnancy?

• A. Fatigue
• B. Nausea
• C. Increased urination
• D. Loss of appetite

Correct answer: D

Rationale: The correct answer is D, 'Loss of appetite.' Loss of appetite is not a common symptom of pregnancy. In fact, many pregnant individuals experience an increase in appetite due to hormonal changes and increased energy needs during pregnancy. Fatigue, nausea, and increased urination are more commonly reported symptoms during pregnancy. Fatigue is often experienced due to hormonal changes and the body's increased metabolic demands during pregnancy. Nausea, commonly known as morning sickness, is a well-known symptom experienced by many pregnant individuals. Increased urination is a common symptom in pregnancy due to hormonal changes leading to increased blood flow to the kidneys and increased fluid processing by the body.

5. What are organisms that break down dead organisms and return nutrients to the environment called?

• A. Producers
• B. Decomposers
• C. Consumers
• D. Parasites

Correct answer: B

Rationale: Decomposers are essential organisms in the ecosystem as they break down dead organisms and organic matter, such as bacteria, fungi, and some insects. By decomposing complex organic materials into simpler forms, they release nutrients back into the environment for other organisms to utilize. Producers (option A) are organisms that generate their own food through photosynthesis; consumers (option C) are organisms that feed on other organisms for energy, and parasites (option D) are organisms that live on or in another organism, benefiting at the host's expense rather than breaking down dead organisms for nutrient recycling.
