Screaming Jelly Baby

The video tutorial demonstrates the energy contained in sugar through a chemical experiment. Using potassium chlorate and a Jelly baby, the experiment shows the exothermic reaction that releases energy in the form of heat, light, and sound. The reaction produces carbon dioxide and water vapor, with a lilac flame due to potassium. The tutorial also discusses different types of sugar, highlighting glucose as a quick energy source, especially in sports drinks.

What is the purpose of using Jelly babies and potassium chlorate in the experiment?

• To create a colorful display

• To measure the melting point of potassium chlorate

• To test the boiling point of sugar

• To demonstrate the energy content in sugar

What is the first step in setting up the experiment?

• Dropping the Jelly baby into the liquid

• Heating the potassium chlorate

• Switching on the fume cupboard

• Turning off the lights

What gas is released when potassium chlorate breaks down?

• Oxygen

• Carbon dioxide

• Hydrogen

• Nitrogen

What is the result of the reaction between the Jelly baby and potassium chlorate?

• A slow melting process

• A quiet reaction

• A violent combustion

• A mild fizzing sound

What color flame is produced during the reaction?

• Lilac

• Red

• Green

• Blue

What are the byproducts of the Jelly baby combustion?

• Carbon dioxide and water vapor

• Sulfur dioxide and water

• Oxygen and hydrogen

• Nitrogen and methane

Why is glucose often included in sports drinks?

• It enhances the flavor of the drink

• It provides a slow release of energy

• It is the most readily absorbed sugar for quick energy

• It helps in muscle recovery
