Procedure: 1. Dissolve one teaspoon or one packet of active yeast in a small amount of warm water. Keep still for about 5 minutes. 2. Dilute a small amount of dishwashing liquid in about ¼ cup of water, or dissolve soap in water. 3. Place about ¼ cup of the dishwashing liquid solution or soap solution into the plastic bottle. Two to three drops of food color can be added and mixed. 4. Add ½ cup of hydrogen peroxide to the soap solution. 5. What is your observation? 6. Add the yeast to the mixture in the bottle. 7. What is your observation? Explain the phenomenon. Which reagent caused the reaction to proceed?

There are 2 moles. 13) If a person were to eat this much glucose all at once (that is a lot of sugar) and all this sugar enters the blood then the person's blood sugar concentration would rise. Imagine that all this glucose is released into the 5 liters of blood that circulate in this person. What would be the molarity of glucose in the blood? Click or tap here to enter text. 14) After each of these glucose molecules enter the blood they are uptaken through cell membranes to enter cells. Within these cells glucose is broken down in a series of steps releasing carbon dioxide along the way. For every molecule of glucose broken down how many molecules of carbon dioxide are created?
