Question

A chemist wants to examine specific chemical reactions and isolate certain products using a controlled experiment. How would the chemist perform this experiment?

Answer 1

To perform a controlled experiment, a chemist can follow several steps: selecting reactants, combining them, controlling variables, observing the reaction, collecting and analyzing the products.

Step-by-step explanation:

Performing a Controlled Experiment to Examine Chemical Reactions and Isolate Products

1. Determine the reaction you want to study and select the appropriate reactants.
2. Measure the mass of each reactant before combining them.
3. Add the reactants together in a test tube or flask.
4. Control the experiment by carefully controlling temperature, pressure, and other relevant factors.
5. Observe the reaction and record any changes, such as color changes, gas production, or temperature changes.
6. Once the reaction has occurred, cool the mixture and collect any products that have formed.
7. Analyze the properties and composition of the products using techniques such as spectroscopy or chromatography.
