1. QuestionMultiple choice

Which observation is strongest evidence that a chemical reaction occurred?

Please select an answer first.

Correct answer: A

The correct answer is A gas forms when two substances are mixed.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Gas formation can indicate that a new substance formed during a chemical reaction.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Gas formation can indicate that a new substance formed during a chemical reaction.

2. QuestionMultiple choice

What happens to atoms during a chemical reaction?

Please select an answer first.

Correct answer: B

The correct answer is They are rearranged into new combinations.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Chemical reactions rearrange atoms, but the atoms themselves are conserved.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Chemical reactions rearrange atoms, but the atoms themselves are conserved.

3. QuestionMultiple choice

Why does a sealed container help scientists test conservation of mass?

Please select an answer first.

Correct answer: C

The correct answer is Matter cannot easily enter or leave the system.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: A closed or sealed system allows the total mass before and after a reaction to be compared fairly.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

A closed or sealed system allows the total mass before and after a reaction to be compared fairly.

4. QuestionMultiple choice

Which property is most useful for identifying a pure substance?

Please select an answer first.

Correct answer: D

The correct answer is A characteristic boiling point.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Characteristic properties such as boiling point can help identify a pure substance.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Characteristic properties such as boiling point can help identify a pure substance.

5. QuestionMultiple choice

What happens to the particles of a substance when it melts?

Please select an answer first.

Correct answer: A

The correct answer is The particles gain enough energy to move past fixed positions.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Melting is a physical change in which particles gain energy and move more freely.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Melting is a physical change in which particles gain energy and move more freely.

6. QuestionMultiple choice

Which change is most likely a chemical change?

Please select an answer first.

Correct answer: B

The correct answer is Iron forms rust in moist air.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Rusting produces a new substance with different properties from iron.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Rusting produces a new substance with different properties from iron.

7. QuestionMultiple choice

Why does increasing temperature often make a reaction happen faster?

Please select an answer first.

Correct answer: C

The correct answer is Particles collide more often and with more energy.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Higher temperature generally increases particle motion and the frequency of effective collisions.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Higher temperature generally increases particle motion and the frequency of effective collisions.

8. QuestionMultiple choice

A student mixes two clear solutions and observes a cloudy solid. What is the cloudy solid called?

Please select an answer first.

Correct answer: D

The correct answer is A precipitate.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: A precipitate is a solid that forms from a solution during a chemical reaction.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

A precipitate is a solid that forms from a solution during a chemical reaction.

9. QuestionMultiple choice

What does pH describe?

Please select an answer first.

Correct answer: A

The correct answer is How acidic or basic a solution is.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: The pH scale describes the acidity or basicity of aqueous solutions.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

The pH scale describes the acidity or basicity of aqueous solutions.

10. QuestionMultiple choice

Which statement best describes a catalyst?

Please select an answer first.

Correct answer: B

The correct answer is It changes the rate of a reaction without being used up.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: A catalyst helps a reaction proceed more quickly or efficiently while remaining available after the reaction.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

A catalyst helps a reaction proceed more quickly or efficiently while remaining available after the reaction.
