Across 1. a solid that is produced from a liquid solution during a chemical change/reaction 6. The substances created after the reaction takes place 8. The composition of a substance changes. Something new is formed 10. An environment where matter can enter or escape 12. Anything that can be observed without changing the identity of the substance. (Tends to be measurable, like boiling point) 13. Happy/Inert Elements (Full Outer Shells) 16. Is a measure of solution that has an excess of H + ions. 18. Temperature at which liquid turns to gas 21. The substances present before the reaction occurs 22. The way a substance may change or react to form other substances. (Like reactivity to other chemicals) 23. The numbers in the front of chemical symbols

Down 2. An environment where matter cannot enter or escape 3. The outer shell of an atom involved in forming bonds to adjacent atoms. Determines the number of bonds an atom can form. 4. Is written as an expression similar to a mathematical equation that can be compared to a recipe that a chemist follows in order to produce desired results 5. During a chemical reaction matter cannot be created or destroyed 7. When bonds between the electrons of atoms are formed or broken 9. The type of matter is not changed, nothing new or different is formed. Change in color, volume shape, etc... 11. Each row in the periodic table. 14. Is a measure of a solution that has an excess of OH - ions. (alkali) 15. Ability to dissolve in a liquid 17. Temperature at which solid turns to liquid 19. Is a measure of how acidic or basic solution is. 20. The numbers behind the chemical symbols
