44. Sort your vocabulary words into 2 categories: H2O and oxygen
word bank:
chemistry formula element
physical change atoms molecule
chemical change compound chemical reaction symbol
chemical bond mixture

45. Word Sort Two categories- H20 and Oxygen
Write each down on your paper in two columns
Place the following words in the categories that they belong:
chemistry, atoms, compound, symbol, formula, molecule, chemical bond, element

46. example
