Always use the upper case for the first character in the element name and the lower case for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Compare: Co - cobalt and CO - carbon monoxide. See your classroom teacher for specific instructions. Note Taking Guide, balancing Equations Worksheet, word Equations Worksheet, need Help? GBP Education offers this video to Georgia Educators at no charge via the GPB Streaming site (Here). Instructions, before viewing an episode, download and print the note-taking guides, worksheets, and lab data sheets for that episode, keeping the printed sheets in order by page number. During the lesson, watch and listen for instructions to take notes, pause the video, complete an assignment, and record lab data. To enter an electron into a chemical equation use - or e. To enter an ion specify charge after the compound in curly brackets: 3 or 3 or 3. Example: Fe3 I- Fe2 I2, substitute immutable groups in chemical compounds to avoid ambiguity. For instance equation C6H5C2H5 O2 C6H5OH CO2 H2O will not be balanced, but XC2H5 O2 XOH CO2 H2O will, compound states like (s) (aq) or (g) are not required. If you do not know what products are enter reagents only and click 'Balance'.
