Across
- 4. Along with carbon, this is used to extract metals such as Iron using a blast furnace
- 7. Particles must collide with enough of this for a reaction to take place
- 9. We chop a reactant up to increase this during a chemical reaction
- 11. This is a type of reaction where a more reactive metals takes the place of a less reactive metal
- 12. This is the name given to metals found in rocks that are mined from the ground
- 13. We find this symbol in a word equation instead of an equals sign
- 14. This is another name for the speed of a reaction
- 16. This 'series' helps us to decide if metals are more reactive that others
- 18. This is something that speeds up a chemical reaction but is not used up in the reaction
- 19. This is an example of a metal that can be extracted just by heating it
Down
- 1. We do this to concentration to speed up the rate of reaction
- 2. This can increase the rate of a reaction
- 3. A new one of these is made during a chemical reaction
- 5. This is the name given to the things you start mix together in an experiment
- 6. This is the name given to the things produced during an experiment
- 8. The metal reactivity series can be used to predict how metals will do this
- 10. This process is used to extract aluminium using electricity
- 15. These metals will react with water
- 17. This 'theory' discusses particles bumping into each other
