Chemistry B - C1, C2, C3 Revision

As I've seen whilst scrolling down the GCSE's section and viewing threads. Most people seem to struggle in chemistry, now it's fun to learn, revise, just a bit difficult. To make your life easier, if your doing the same exam board as I am, OCR Gateway B, I can help you a little.

C1 - Carbon Chemistry

Remember, each module contains 8 topics.
The 1st module consists of the following topics:

Making crude oil useful

Using carbon fuels

Clean air

Making polymers

Designing polymers

Cooking food and additives

Smells

Paints and Pigments



I'll later on put some questions related to C1 and C2. Mostly done C3 questions so far.

C2 - Chemical Resources


The 2nd module consists of the following topics:

The structure of the Earth

Construction Materials

Metals and alloys

Making cars

Making ammonia

Acids and bases

Fertilisers and crop yields

The chemistry of Sodium Chloride



C3 - Chemical Economics


The 3rd module consists of the following topics:

Rate of reaction 1 Reaction times and rates

Rate of reaction 2 Reaction rate and changing conditions

Rate of reaction 3 Explosions and catalysts

Reacting masses

Percentage yield and atom economy

Energy, Batch or continuous?

Allotropes of carbon and nanochemistry



Normal questions on the C3 Module: - Not exam style questions, these were all made by me, some include C1 and C2. These are revision based questions, I use these to revise for my C1,C2,C3 test whenever I have one. Then, I develop them into exam questions and really see my intelligence, because in the exam, they'll give more longer or difficult questions.

Teacher questions:

I'll write up the exam questions tomorrow, still got to make them.
If you want the answers to any of the questions I posted on this thread, whether it's the teacher questions or my own questions, feel free to post on this thread or private message me. I'll send my own answers for each questions.

Graphite isn't a rock. Maybe you mean granite?
What the heck are allotropes? Oo0

Different structures of an element. For example carbon has graphite, graphene, diamond and buckminsterfullerene, plus a few more obscure ones

Ooh, like oxygen has o2 and ozone?

Yes, you probably don't need to know that for GCSE though
