      The mass of the ashes and smoke is equal to the mass of the wood before it was burned.

      Explanation: The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction. When wood is burned, it transforms into ashes and gases, but the total mass remains constant. Therefore, the mass of the ashes and smoke after the burning process is equal to the initial mass of the wood.
