The answer will appear below, Always use the upper case for the first character in the element name and the lower case for the second character. Reaction stoichiometry could be computed for a balanced equation. Examples: Fe, Au, Co, Br, C, O, N, F.     Compare: Co - cobalt and CO - carbon monoxide, 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}. If you do not know what products are enter reagents only and click 'Balance'. Examples: Fe, Au, Co, Br, C, O, N, F.     Compare: Co - cobalt and CO - carbon monoxide, 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}. Enter either the number of moles or weight for one of the compounds to compute the rest. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents. Substitute immutable groups in chemical compounds to avoid ambiguity. Write down the unbalanced equation ('skeleton equation') of the chemical reaction. Compound states [like (s) (aq) or (g)] are not required. Substitute immutable groups in chemical compounds to avoid ambiguity. If you do not know what products are enter reagents only and click 'Balance'.
