• Carbon cannot form any structures.

What happens during a chemical reaction involving carbon?

• Carbon reactions always produce heat without exception.

• Carbon cannot react with other elements.

• Carbon can react with other elements to form new compounds, often releasing or absorbing energy.

• Carbon only exists in its pure form during reactions.

Give an example of a reaction that involves carbon compounds.

• Photosynthesis: 6CO2 + 6H2O -> C6H12O6 + 6O2

• Formation of sodium chloride: Na + Cl2 -> NaCl
