Explaining the change in mass • Iron is a solid. • Oxygen is a gas. • Iron reacts with oxygen in the air to form a new compound called iron oxide. • During the reaction, the atoms of iron and oxygen combine together. • Iron oxide is a solid. It can be seen on the surface of the iron wool. • Because the oxygen has added to the iron, the iron wool is heavier than at the start.
