Yes, it makes sense because we expect products and reactants to have different properties. During a chemical reaction, the bonds between atoms in the reactants are broken and new bonds are formed to create the products. This rearrangement of atoms can result in different properties in the products compared to the reactants. In the case of methane (CH4) burning in the presence of oxygen (O2) to produce carbon dioxide (CO2) and water (H2O), the properties of methane and carbon dioxide are different. Methane is flammable because it can support combustion and readily react with oxygen to produce heat and light, while carbon dioxide is not flammable as it does not support combustion.
