1. QuestionMultiple choice

Which statement best describes atoms during a chemical reaction?

Please select an answer first.

Correct answer: A

The correct answer is Atoms are rearranged into new combinations..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: A chemical reaction rearranges atoms, so the same atoms form new substances.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

A chemical reaction rearranges atoms, so the same atoms form new substances.

2. QuestionMultiple choice

Which observation is strongest evidence that a new substance formed?

Please select an answer first.

Correct answer: B

The correct answer is A solid precipitate forms when two liquids are mixed..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Formation of a precipitate can indicate that a new solid substance formed during a reaction.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Formation of a precipitate can indicate that a new solid substance formed during a reaction.

3. QuestionMultiple choice

In a closed container, the total mass before a chemical reaction is 48 grams. What is the total mass after the reaction?

Please select an answer first.

Correct answer: C

The correct answer is 48 grams.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Conservation of mass means the total mass remains 48 grams in a closed system.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Conservation of mass means the total mass remains 48 grams in a closed system.

4. QuestionMultiple choice

Which change is a physical change?

Please select an answer first.

Correct answer: D

The correct answer is Water freezing into ice.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Freezing changes the state of water but does not create a new substance.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Freezing changes the state of water but does not create a new substance.

5. QuestionMultiple choice

What does a balanced chemical equation show?

Please select an answer first.

Correct answer: A

The correct answer is The same number of each type of atom on both sides.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: A balanced equation follows conservation of matter by showing equal atom counts for each element.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

A balanced equation follows conservation of matter by showing equal atom counts for each element.

6. QuestionMultiple choice

Which particle has a negative electric charge?

Please select an answer first.

Correct answer: B

The correct answer is An electron.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Electrons have negative charge, while protons are positive and neutrons have no charge.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Electrons have negative charge, while protons are positive and neutrons have no charge.

7. QuestionMultiple choice

A solution has a pH of 3. Which description is most accurate?

Please select an answer first.

Correct answer: C

The correct answer is It is acidic..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Values below 7 on the pH scale are acidic.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Values below 7 on the pH scale are acidic.

8. QuestionMultiple choice

Which factor usually increases the rate at which a solid dissolves in water?

Please select an answer first.

Correct answer: D

The correct answer is Stirring the mixture.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Stirring brings fresh solvent into contact with the solid and can speed dissolving.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Stirring brings fresh solvent into contact with the solid and can speed dissolving.

9. QuestionMultiple choice

What is the best evidence that a substance is a pure compound?

Please select an answer first.

Correct answer: A

The correct answer is It has a fixed composition and characteristic properties..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: A compound has elements in a fixed ratio and has properties different from the elements that form it.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

A compound has elements in a fixed ratio and has properties different from the elements that form it.

10. QuestionMultiple choice

If a reaction releases thermal energy to its surroundings, how is the reaction classified?

Please select an answer first.

Correct answer: B

The correct answer is Exothermic.
