| Bạn đang xem: Star Instructions on balancing chemical equations:Enter an equation of a chemical reaction & click "Balance". The answer will appear belowAlways use the upper case for the first character in the element name & the lower case for the second character.Examples: Fe, Au, Co, Br, C, O, N, F. Compare: co - cobalt và CO - carbon monoxideTo enter an electron into a chemical equation use - or e to lớn enter an ion, specify charge after the compound in curly brackets: +3 or 3+ or 3. Example: Fe3+ + I- = Fe2+ + I2Substitute immutable groups in chemical compounds to lớn avoid ambiguity. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O willCompound states |
