To write a balanced chemical equation for the reaction between sulfur and oxygen, follow these steps:

1. Name each substance in your equation:
- Sulfur is represented by the symbol "S".
- Oxygen is represented by the symbol "O2".

2. Write the balanced chemical equation:
- The reaction between sulfur and oxygen forms sulfur dioxide.
- The balanced equation is:
S + O2 → SO2

3. Draw a picture of your equation:
- Represent sulfur with yellow color.
- Represent oxygen with red color.
- Draw a simple diagram showing sulfur and oxygen combining to form sulfur dioxide.

4. Use plastic beads and plasticine to build the reactants:
- Use yellow plasticine or beads to represent sulfur.
- Use red plasticine or beads to represent oxygen.

5. Show how the reactant atoms rearrange to form the product:
- Arrange the yellow beads (sulfur) and red beads (oxygen) close together to illustrate the reaction.
- Rearrange the beads to show the formation of sulfur dioxide.

Repeat the same steps for the reaction between carbon and oxygen:

1. Name each substance:
- Carbon is represented by the symbol "C".
- Oxygen is represented by the symbol "O2".

2. Write the balanced chemical equation:
- The reaction between carbon and oxygen forms carbon dioxide.
- The balanced equation is:
C + O2 → CO2

3. Draw a picture of your equation:
- Use black color for carbon this time.
- Draw a diagram illustrating the combination of carbon and oxygen to produce carbon dioxide.

4. Use plastic beads and plasticine to build the reactants:
- Use black plasticine or beads to represent carbon.
- Use red plasticine or beads to represent oxygen.

5. Show how the reactant atoms rearrange to form the product:
- Arrange the black beads (carbon) and red beads (oxygen) to demonstrate the reaction.
- Rearrange the beads to show the formation of carbon dioxide.

By following these steps, you can effectively represent and understand the chemical reactions between sulfur and oxygen, as well as carbon and oxygen.
