Chemical Reactions and Safety Practices

Laura Ibarra Kane and Matthew Dantzler from the South Carolina State Museum demonstrate two chemical reactions. Laura starts with a simple Alka-Seltzer experiment, explaining how it reacts with water to create gas and pressure. Matthew then conducts a larger experiment using dish soap, hydrogen peroxide, and sodium iodine, emphasizing safety precautions. The video showcases both small and large-scale chemical reactions, suitable for classroom or home experiments.

Who are the educators presenting the chemical reaction experiments?

• Alice Johnson and Bob Brown

• Emily White and Michael Green

• John Doe and Jane Smith

• Laura Ibarra Kane and Matthew Dantzler

What happens when an Alka-Seltzer tablet is placed in water?

• It remains unchanged

• It starts to fizz

• It dissolves without any reaction

• It changes color

What is used to demonstrate the pressure build-up in the film canister experiment?

• A plastic bottle

• A glass jar

• A film canister

• A metal tin

What safety precautions are necessary for the large-scale chemical reaction?

• No precautions needed

• Only goggles are required

• Gloves, goggles, and tying back long hair

• Just gloves are enough

Which of the following is NOT used in the large-scale chemical reaction?

• Dish soap

• Vinegar

• Hydrogen peroxide

• Sodium iodine

What concentration of hydrogen peroxide is used in the large-scale reaction?

• 50%

• 3%

• 30%

• 6%

What is the purpose of swirling the dish soap and hydrogen peroxide together?

• To cool down the mixture

• To separate the components

• To ensure a better chemical reaction

• To make the solution colorful

What is the result of adding sodium iodine to the mixture in the large-scale reaction?

• No visible reaction

• A large and impressive chemical reaction

• A change in color only

• A small fizzing reaction

What is the main reason for using safety gloves during the large-scale reaction?

• To look professional

• To avoid staining hands

• To prevent itching from hydrogen peroxide

• To keep hands warm

What is the educational purpose of these chemical reaction demonstrations?

• To entertain the audience

• To teach about chemical reactions and safety

• To promote the museum's gift shop

• To showcase the museum's collection
