A list of things that hasn't come up...
The ________________ has strict regulations to control chemical processes. -
- Explain the limitations of using some catalysts, and explain why biological catalysts are better
- Draw methane, ethane, propane and butane. What are their molecular formulas ?
- Explain why alkanes are unreactive and why alkenes are reactive.
- Describe the reaction of alcohols with sodium and explain how this compares with the reactions of water and alkanes with sodium.
- Explain how genetically modified E. coli bacteria can be used to convert waste biomass from a range of sources into ethanol.
-Give two smells/tastes that carboxylic acids are responsible for
- Give two uses of esters
- Explain where the feedstocks of the Haber process come from
-Explain the effect of pressure and temperature on the Haber Process.
- Describe and compare paper and thin-layer chromatography
- Describe gas chromatography - Explain the titration process
- What is the unit for concentration?
- Explain how you would make up a standard solution
-Carry out a titration calculation
6 mark question -fermentation/Haber process/comparing reactions of alkanes, alkenes, alcohols and carboxylic acids with sodium/ Explain how a titration is carried out/ Explain the process of making a standard solution
Although from today's B7 paper, it looks like they're taking last years paper and just rewording it and adding some waffle in between
