Yes, the first chemical reaction (without the enzyme) acted as a control.

A chemist measure mass, volume, concentration, flammability point, resistance to corrosion, etc.
Of course, this is a chemist.
Controls are used in experiments to provide a baseline for comparison with the group that is being tested. By having a control group that does not receive the treatment or intervention, researchers can better assess the effects of the manipulated variable. This allows for a more accurate interpretation of the results and helps to minimize bias and confounding factors.
The answer depends on what the experiment is.

The chemist worked for a major lab.
They use it
Bioassay test panels includes a tested series of frequently requested samples or disease state samples with healthy controls to do comparitive experimental research.
He was a chemist. It's just a job description.

Example sentence - He completed his homework with adequate effort.
I can only hope that my studies were adequate.

Scientists try to control for experimental bias.An experimental bias often goes unrecognized if the student does not carefully consider sources of potential biases.A desire for a specific outcome is an experimental bias.

A chemist uses lab equipment, such as beakers, graduated cylinders, lab googles, etc.
