🆕 New Concept Discovered: Chemical Reaction Components
The starting ingredients versus the final results

Step 1: Define the components of a chemical reaction

In any chemical reaction, we start with certain substances and end up with different ones.

• Reactants are the starting materials that go into the reaction.
• Products are the entirely new substances that are created as a result of the reaction.
• Catalysts are substances that speed up the reaction without being consumed.

Step 2: Evaluate the given options

• A) The substance that speeds up the reaction: This describes a catalyst, not a product.
• B) The new substance formed: This matches the definition of a product (the end result of the chemical change).
• C) The starting material: This describes a reactant, not a product.
• D) The energy released: While energy can be released (in exothermic reactions), it is a byproduct of the process rather than the chemical substance itself.

Answer:

B) The new substance formed
