When wood burns, a small amount of ashes is produced and gas is given off. How does this reaction demonstrate the law of conservation of mass?.
The law of conservation of mass states that matter can neither be created nor destroyed. When wood burns, the mass of the wood is converted into a small amount of ashes and gas. The total mass of the ashes and gas is equal to the mass of the wood before it was burned, demonstrating that the law of conservation of mass holds true.
The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction; it can only be rearranged. When wood burns, it undergoes a chemical reaction known as combustion. During combustion, the wood reacts with oxygen from the air, releasing energy in the form of heat and light.
In this reaction, the wood combines with oxygen molecules (O2) to produce carbon dioxide (CO2) and water vapor (H2O). Additionally, some of the wood's components, such as minerals and impurities, are left behind as ashes. It is important to note that the gas released during combustion, as well as the ashes produced, have a combined mass equal to the original mass of the wood.
This demonstrates the law of conservation of mass because even though the wood appears to have transformed into gas and ashes, the total mass of the products, including the carbon dioxide, water vapor, and ashes, is equal to the mass of the original wood. No mass is lost or gained during the combustion process, confirming the conservation of mass.
The reaction of wood burning does indeed demonstrate the law of conservation of mass. This law states that matter cannot be created or destroyed; it can only change forms. In the case of wood burning, the initial mass of the wood is equal to the sum of the mass of the ashes produced and the gas given off.
When wood burns, it undergoes a process called combustion. During combustion, the wood reacts with oxygen from the air, transforming the wood into carbon dioxide gas and water vapor. This chemical reaction releases energy in the form of heat and light.
Even though the wood appears to disappear during the burning process, its mass is conserved. The resulting ashes are the solid remnants of the wood, consisting mainly of carbon and other minerals present in the wood. The gases produced, mainly carbon dioxide and water vapor, have mass as well.
By measuring the mass of the wood before and after burning, you would find that the total mass remains the same. This confirms the law of conservation of mass, as the mass of the products (ashes and gases) equals the initial mass of the wood.
