According to the laws of combustion, what does conservation of matter state?

The principle of conservation of matter, also known as the law of conservation of mass, asserts that mass cannot be created or destroyed in a chemical reaction. This means that during a combustion process, the total mass of the reactants must equal the total mass of the products.

In a combustion reaction, the reactants (such as a fuel and an oxidizer) combine to produce products (such as carbon dioxide and water) while maintaining the same overall mass before and after the reaction. This principle is fundamental to understanding chemical processes, as it emphasizes that all atoms present in the reactants are accounted for in the products—none are lost, and none are newly created.

This fundamental idea underpins various calculations in power engineering, including balancing chemical equations and determining energy outputs and efficiencies in combustion systems. Moreover, it serves as a foundation for understanding other conservation principles in physics and chemistry, making it crucial knowledge for anyone studying combustion or related processes in engineering.
