What is required for a chemical reaction to occur?

For a process to be classified as a chemical reaction, i.e., one where a chemical change takes place, a new substance must be produced. The formation of a new substance is nearly always accompanied by an energy change, and often with some kind of physical or observable change.

What are the reactants products and chemical reactions?

As a demonstration, light a candle and explain what is happening using the terms reactants, products, and chemical reaction. Explain that in most chemical reactions, two or more substances, called reactants, interact to create different substances called products.

How is a chemical reaction different from a physical change?

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. The properties of the products are different from those of the reactants. Chemical reactions differ from physical changes, which include changes of state, such as ice melting to water…
