Final answer:
In a Chemistry lab procedure, recording the time to complete a chemical reaction is a key step. It involves data collection, which is essential for verifying results and is a critical part of testing a hypothesis.
Step-by-step explanation:
Steps in a Lab Procedure
As part of the process of conducting a lab in Chemistry, there are several key steps outlined by the scientific method. Option C, record the time to complete a chemical reaction, is most likely to be a part of a lab procedure. This is because recording data gleaned from the experiment is a critical part of testing a hypothesis and is crucial for analyzing results and drawing valid conclusions.
Writing a hypothesis (Option A) typically takes place before an experiment is conducted, and writing a title (Option B) is usually done when compiling the final lab report after the experiment. Creating a question about the cause of a chemical reaction (Option D) is the initial step that leads to formulating a hypothesis, not part of the active lab experiment itself.
Detailed, reliable data collection is essential for the verification of results, as repeatability is a cornerstone of the scientific method. This step involves making systematic observations or measurements under controlled conditions.
