If you do not know what products are enter reagents only and click 'Balance'. So it is limiting reagent question. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. The equation for the reaction is: Zn(s) + 2HCl(aq) ---> H2(g) + ZnCl2(aq) A piece of zinc is dropped into 1.00 L of 0.100 M HCl and the following data were obtained: Chemistry. Before there is a transfer of charges between objects, they are uncharged. So, you would have Zn 2+ (aq) + S 2-(aq) ==> ZnS(s) as the NET IONIC EQUATION 1831 鋅 - Zn.
