Across 1. C2H5OH (l) 5. the father of modern chemistry 7. The relative attraction that an atom has for shared electrons in a covalent bond 9. a solution that conducts an electrical current 10. a shared pair of electrons between two atoms is represented by a simple line 11. happens when crystals of ionic compounds during the solution process separate into ions 15. a swedish chemist who proposed a conceptual definition of acids and bases 16. a solution which will not conduct an electrical current 20. exists in nonpolar molecules, temporary dipoles attract each other 21. an electrostatic attraction between particles 23. within 24. a substance that fills and assumes the shape of it's container, diffuses rapidly, and mixes readily. 25. formation of the total negative charge of ions from polar molecules

Down 2. mass is conserved in a chemical reaction 3. Element + Element = compound 4. stiochiometry involving the measurement of gravity or mass as opposed to measurement of solution volume or gas volume. 6. only exist between two atoms of the same nonmettalic elements because they are exactly the same 8. add enough energy to break bonds inside molecules 12. defined as 25C and 100kPa 13. the lowest possible temperature 14. discovered the dephlogisticated air 17. the product of the pressure and volume of a gas sample is proportional to it's absolute temperature in kelvins 18. the force per unit area measured in SF units of pascals 19. atoms with a different number of neutrons 21. as the temperature of a gas increases the volume increases proportionally, provided that the pressure and chemical amount of gas remain constant 22. as the pressure on a gas increases the volume of the gas decreases proportionallly, provided that the temperature and chemical amount of gas remain constant
