Hypothesis #3: Using potassium iodide (KI) will produce a larger volume of foam than using yeast The scientists decided that they will combine 20.0 mL of hydrogen peroxide, 1.0 mL of dish soap, three drops of food coloring, and 0.5 g of either Kl or yeast. All reagents will be at 23C. Here is the scientist's plan and results: Experiment Reagent #1 Reagent #2 Reagent #3 Volume of foam 1 2 3 4 5 6 7 8 10% H202 10% H2O2 10% H2O2 10% H2O2 35% H202 35% H202 35% H2O2 35% H2O2 blue food coloring blue food coloring red food coloring red food coloring blue food coloring blue food coloring red food coloring red food coloring KI yeast KI yeast KI yeast KI yeast 3.5 2.1 3.5 2.1 4.2 2.7 4.2 2.7 6. Classify each of the following variables in the experiment as independent, dependent, or controlled. (1/2 point each). There are more than one independent variables in this experiment. a volume of dish soap b. color of food coloring: C. concentration of H2O2: d. Temperature
