Across
- 2. they have delocalised electrons in each carbon, but they dont conduct electricity because the delocalised electron cannot move through molecules of this substance.
- 3. every carbon contains 4 covalent bonds, they have a high ,melting point becuase their covalent bonds are very strong.
- 4. occurs when iron reacts with the oxygen and water
- 6. a way to prevent iron from rusting, it is a type of barrier method
- 10. solid that is dissolved by the liquid
- 12. when particles go from a high concentration to a low concentration
- 13. their mass is 1/1836 (or 0) and their charge is negative 1
- 14. atoms that have the same element, same number of protons but different number of neutrons
- 15. liquid that dissolves the solid
Down
- 1. using a filter paper to separate components of a mixture
- 5. when the solute dissolves in the solvent
- 7. where the solute cannot dissolve in the solvent
- 8. you can calculate the number of it by atomic mass - atomic number
- 9. the solute that is separated from the solution after being filtered
- 11. their mass is one and their charge is positive 1
