Presentation Transcript

  1. Practical Work for Learning Combustion of iron wool

  2. You will be able to use a scientific model to explain what happens to the mass of iron wool during combustion Learning outcome

  3. What will happen when the iron wool combusts?Make your prediction. A B C ?

  4. Iron is a solid

  5. Draw diagrams to show the particles.

  6. 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.
