Question

part c why do you use the same amount of baking soda and same amount of liquid for each combination?

Explanation:

Using the same amount of baking soda and liquid for each combination is to control variables in an experiment. This ensures that the only factor affecting the outcome (e.g., reaction rate, product formation) is the type of liquid or other intended variable, not the quantity of reactants. It follows the scientific method's principle of controlling variables to obtain valid, comparable results.

Answer:

To control variables in the experiment, ensuring that only the intended factor (e.g., type of liquid) affects the outcome, so results are valid and comparable.
