ReactantsProducts Mg11✔️ O88✔️ H3232✔️ N66✔️ Step 3: Verify that the equation is balanced Since there are an equal number of atoms of each element on both sides, the equation is balanced. Mg(OH)2+6NH4OH = (Mg(NH3)6)(OH)2+6H2O ...
The balanced net ionic equation includes only species that are involved in the reaction. It can be found by removing ions that occur on both the reactant and product side of the complete ionic equation. Mg(CO3)(s) = CO32-(aq) + Mg2+(aq) ...
Magnesium metal is added to 15.7M hydrochloric acid and reacts according to the following balanced equation: Mg(s) + 2 HCl(aq) MgCl2 (aq) + H2(g) a. What mass of magnesium will react with 8.5 liters of 0.7 M hydrochloric acid? 15.95X10^-3mol/2=2. ...
