A formula is like NaCl for table salt, or H2O for water.
Formulas are made of:
- One or more element symbols (like the C, H, and O in glucose: C6H12O6)
- Sometimes there are subscripts (like the 6, 12, and 6 in glucose)
- Sometimes there are parentheses (like in Ba(NO3)2 )
Make sure you read the footnotes at the bottom of the worksheet-- they will simplify things for you!
P.S. If you're worried that you'll have more homework next time (since the assembly put us behind) you could go on Skyward and do the "Defining Matter" assignment early! :)
