Exploring the Elephant Toothpaste Reaction

Front

What is a chemical change?

Back

A process where substances combine or break apart to form new substances, often accompanied by energy changes, color changes, or gas production.

Front

What is the elephant toothpaste reaction?

Back

A chemical reaction that produces a large amount of foam, typically involving the decomposition of hydrogen peroxide.

Front

What is hydrogen peroxide?

Back

A chemical compound (H2O2) that is a colorless liquid used as a disinfectant and bleaching agent.

Front

What role does a catalyst play in a chemical reaction?

Back

A substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What is yeast?

Back

A living organism used as a catalyst in the elephant toothpaste experiment, which helps decompose hydrogen peroxide.

Front

What is foam?

Back

A mass of small bubbles formed when gas is trapped in a liquid.

Front

What is the main observation in the elephant toothpaste experiment?

Back

The production of foam.

Front

What is the decomposition of hydrogen peroxide?

Back

The breakdown of hydrogen peroxide into water and oxygen gas, often accelerated by a catalyst.

Front

What is the effect of temperature on chemical reactions?

Back

Increasing temperature generally speeds up chemical reactions by providing more energy to the reacting molecules.

Front

What is an example of a physical change?

Back

Melting ice or boiling water, where the substance changes state but not its chemical composition.
