Exam Response (energy)
What is it?
Typical tasks: fraction table (b.p., size, viscosity); cracking products; complete vs incomplete; named pollutants; nuclear waste vs CO2; renewable intermittency; footprint slogan. No refinery design. No weapons. No enrichment. Energy question: name source, one advantage, one disadvantage, one pollutant if fossil. Compare fuels on emissions and renewability, not slogans alone — one advantage and one drawback each.
In simple words
- Typical tasks: fraction table (b.p., size, viscosity); cracking products; complete vs incomplete; named pollutants; nuclear waste vs CO2; renewable intermittency; footprint slogan.
- 1. OIL: Mixture.
- 2. OTHER: Nuclear civilian + waste.
- Exam reminder: Worked 4-mark cracking: large alkanes -> smaller alkanes + alkenes more petrol and ethene (named demand) thermal or catalytic (names) not a reactor design Nuclear: mention waste and safety without weapon or medical dose detail.
Important terms
EXAM RESPONSE (ENERGY): Typical tasks: fraction table (b.p., size, viscosity); cracking products; complete vs incomplete; named pollutants; nuclear waste vs CO2; renewable intermittency; footprint slogan.
1. OIL: Mixture.
2. OTHER: Nuclear civilian + waste.
What you should learn
- Explain exam response (energy) in simple chemical language.
- Connect 1. oil with 2. other using equations, observations, or trends where needed.
- Answer a short Federal Board question with the correct terms and a clear reason.
Examples
- Top volatile
- Bitumen bottom
- Catalytic cracking named
OIL
Mixture. Fractions named. Cracking named. Ethene feedstock. Combustion cards from air chapter. Cracking equation: show long alkane -> short + alkene.
OTHER
Nuclear civilian + waste. Solar/wind intermittent. H2 as clean at use. Biomass recent carbon. Balanced compare. Renewable vs non-renewable definition with examples.

WHAT — EXAM RESPONSE (ENERGY)
Typical tasks: fraction table (b.p., size, viscosity); cracking products; complete vs incomplete; named pollutants; nuclear waste vs CO2; renewable intermittency; footprint slogan. No refinery design. No weapons. No enrichment. Energy question: name source, one advantage, one disadvantage, one pollutant if fossil. Compare fuels on emissions and renewability, not slogans alone — one advantage and one drawback each.
WHY — Why this topic matters
EXAM RESPONSE (ENERGY) is an independent FBISE learning unit because students must use its definitions, conditions, equations, or trends separately in explanations and calculations.
HOW — How it works
OIL: Mixture. Fractions named. Cracking named. Ethene feedstock. Combustion cards from air chapter. Cracking equation: show long alkane -> short + alkene. Examples: Top volatile; Bitumen bottom; Catalytic cracking named. OTHER: Nuclear civilian + waste. Solar/wind intermittent. H2 as clean at use. Biomass recent carbon. Balanced compare. Renewable vs non-renewable definition with examples. Examples: CO2; Waste; Reliability; No weapons. Worked 4-mark cracking: large alkanes -> smaller alkanes + alkenes more petrol and ethene (named demand) thermal or catalytic (names) not a reactor design Nuclear: mention waste and safety without weapon or medical dose detail.

Remember
- stage names
Examples
- Top volatile
- Bitumen bottom
- Catalytic cracking named
OTHER
Nuclear civilian + waste. Solar/wind intermittent. H2 as clean at use. Biomass recent carbon. Balanced compare. Renewable vs non-renewable definition with examples.
Remember
- axes
Examples
- CO2
- Waste
- Reliability
- No weapons
Remember
- tower = b.p.
- crack = smaller + alkene
- demand + alkenes
- exams only
- stage names
- axes
- tower = b.p.
- crack = smaller + alkene
How the ideas connect
Worked 4-mark cracking: large alkanes -> smaller alkanes + alkenes more petrol and ethene (named demand) thermal or catalytic (names) not a reactor design Nuclear: mention waste and safety without weapon or medical dose detail.
Deeper understanding
Go beyond memorising Exam Response (energy). Connect the definition to reasons, relationships, exceptions, and exam wording.

Common exam traps
- Do not confuse 1. OIL with 2. OTHER; state the difference before giving an example.
- Writing only “tower = b.p.” is not enough. Explain what it means in a complete sentence.
