A chemical reaction that occurs when a substance combines with oxygen, producing heat and light.

Front

What is the principle behind the conservation of mass in chemical reactions?

Back

Mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.

Front

What is the pH scale used for?

Back

To measure the acidity or basicity of a solution.

Front

What is the difference between an acid and a base?

Back

Acids donate protons (H⁺) while bases accept protons.

Front

What is the role of a catalyst in a chemical reaction?

Back

A catalyst speeds up a chemical reaction without being consumed in the process.
