Mg(NO3)2 + H2O --> MgOH+ + H+ + 2NO3-MgOH+ is the precursor to Mg(OH)2(s) Mg + 2H2O ---> Mg2+ + 2OH- + H2 The states are obvious. Using the equation, Mg (s) + 2HCl (aq) MgCl2 (aq) + H2 (g), if 24.3 g of Mg and 75.0 g of HCl are allowed to chemistry When magnesium metal and an aqueous solution of hydrochloric acid combine, they produce an aqueous solution of magnesium chloride and hydrogen gas. We must first convert the grams of Mg(OH)2 to moles and then moles to molecules of Mg(OH)2. Mg + O2 --> MgO ... What Coefficients must be added and where to balance the above equation? The balanced equation will appear above. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. To write out a net ionic equation, you first have to identify which compounds dissociate into ions and which don't, then write out a complete ionic equation. Li ( 1. LiNO3 + 1. Enter either the number of moles or weight for one of the compounds to compute the rest. Use uppercase for the first character in the element and lowercase for the second character.
