Have you ever sat around a campfire or watched flames flicker in a fireplace? The burning of wood is a chemical reaction. A chemical reaction always involves changes in chemical bonds that join atoms in compounds. The elements or compounds that enter into a chemical reaction are called reactants. The elements or molecules produced by a chemical reaction are called products. As wood burns, molecules of cellulose are broken down and combine with oxygen to form carbon dioxide and water vapor, and energy is released. What are the reactants when wood burns? What are the products when wood burns?

The correct answer is -

Reactants - oxygen and cellulose.

Products - carbon dioxide and water (carbon residues sometimes)

Explanation:

Burning wood is a chemical reaction that involves a reaction between reactants and produces products with energy. In this chemical reaction, the reactants that take part are oxygen present in the atmosphere and cellulose (wood made up of cellulose).

In this reaction a lot of energy or heat loss takes place and at the end of the reaction carbon dioxide and water produces. however, sometimes other substances also present.

this is a good question! i'll do some research and come back when i have the answer!

sodium i think the chemical element of atomic number 11, a soft silver-white reactive metal of the alkali metal group.
