The answer will appear belowAlways 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 monoxideTo enter an electron into a chemical equation use - or e 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 avoid ambiguity. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O willCompound statesXem thêm: Thế Nào Là Tơ Poliamit Là? Sơ Lược Tí Về Tơ Hóa Học Nhé
In many cases a complete equation will be suggested.Reaction stoichiometry could be computed for a balanced equation. Enter either the number of moles or weight for one of the compounds khổng lồ compute the rest.Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. The limiting reagent row will be highlighted in pink.Examples of complete chemical equations to lớn balance:
