1. QuestionMultiple choice

Which observation is evidence that a chemical reaction occurred?

Please select an answer first.

Correct answer: A

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

  1. Identify the evidence: Read the scenario, model, or data and identify the scientific evidence provided.
  2. Apply the science idea: The formation of a gas can indicate that new substances formed.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

The formation of a gas can indicate that new substances formed.

2. QuestionMultiple choice
