Edexcel IAL Chemistry AS 4.16 Carbon neutrality
Edexcel IAL Chemistry AS 4.16 Carbon neutrality
Identify the carbon source, account for combustion emissions and compare them with carbon absorbed during growth or captured before judging the overall claim.
How this is tested
- Explain biofuel carbon neutrality by matching combustion release with plant uptake.
- Evaluate CCU fuel blends by separating captured carbon from fossil-fuel emissions.
