Question

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!! This investigation is a controlled experiment, so you can change only one variable at a time. Decide whether you’ll change the amount of baking soda or the amount of vinegar. Give a reason for your choice.

Answer 1

I would choose the vinegar before baking soda because the baking soda is what is making the chemical reaction with the vinegar. Both need eachother but the vinegar is a less powerful reactant than the baking soda.
