1. Which sentence uses the correlative conjunction 'either/or' correctly?

• A. You can either come to the party or stay home.
• B. Either she will go to the concert, or he will.
• C. I'm not sure whether I should go swimming or running.
• D. He likes both pizza and pasta, so he can have either.

Correct answer: A

Rationale: Option A uses the correlative conjunction 'either/or' correctly by presenting two exclusive options. The structure 'either...or' is used to show a choice between two alternatives, and in this sentence, it clearly presents the options of coming to the party or staying home. Choice B incorrectly separates the options with a comma after 'either,' disrupting the correlative conjunction pair. Choice C uses 'whether' instead of 'either/or,' which changes the meaning and structure. Choice D uses 'either' incorrectly, as it should be followed by 'or' to form the correlative pair.

2. How many milliliters are in 2 liters?

• A. 2000 mL
• B. 20,000 mL
• C. 200 mL
• D. 2 mL

Correct answer: A

Rationale: There are 1000 milliliters in 1 liter, so 2 liters equal 2000 milliliters. The conversion is based on the fact that the prefix 'milli-' means one-thousandth. Therefore, the correct answer is 2000 mL. Choice B, 20,000 mL, is incorrect as it multiplies 2 liters by 10. Choice C, 200 mL, is incorrect as it divides 2 liters by 10. Choice D, 2 mL, is incorrect as it incorrectly assumes that 2 liters is equal to 2 milliliters.

3. After a twelve-hour workday, James was exhausted when he heard the news.

• A. .
• B. ;
• C. ,
• D. —

Correct answer: C

Rationale: The comma (,) is used to separate the introductory clause 'After a twelve-hour workday' from the main clause 'James was exhausted when he heard the news.' This punctuation correctly indicates the relationship between the two clauses without interrupting the flow of the sentence. Choice A (.), a period, would create two separate sentences, which is not appropriate in this context. Choice B (;) is too strong of a pause and semicolons are typically used to connect closely related independent clauses. Choice D (—) is an em dash, which is used to set off an abrupt break or interruption in the sentence, not to separate an introductory clause from the main clause.

4. When baking soda (sodium bicarbonate) reacts with vinegar (acetic acid), what type of reaction occurs?

• A. Combustion
• B. Double displacement
• C. Decomposition
• D. Synthesis

Correct answer: B

Rationale: When baking soda (sodium bicarbonate) reacts with vinegar (acetic acid), a double displacement reaction occurs. In this reaction, the positive ions in baking soda switch places with the positive ions in vinegar to form water, carbon dioxide, and a salt. Combustion involves a reaction with oxygen to produce heat and light energy. Decomposition is the breakdown of a compound into simpler substances, which is not the case in the given reaction. Synthesis is the combination of substances to form a more complex compound, which is also not the type of reaction observed when baking soda and vinegar react.

5. Which two types of elements are most likely to form an ionic bond?

• A. Two elements that are in the same period.
• B. Two elements that are non-metals and have p orbitals.
• C. One element that is a transition metal with d orbitals and one element that is a metal with s orbitals.
• D. One element that is a metal with s orbitals and one element that is a nonmetal with p orbitals.

Correct answer: D

Rationale: Ionic bonds typically form between a metal, which donates electrons from its s orbital, and a nonmetal, which accepts electrons into its p orbital. This transfer of electrons leads to the formation of an ionic bond. Choice A is incorrect as elements in the same period may vary significantly in their properties. Choice B is incorrect because ionic bonds are usually formed between a metal and a nonmetal, not two nonmetals. Choice C is incorrect because transition metals generally form complex ions through the sharing of electrons, not typical ionic bonds.
