Mg+H2O=MgOH+H2
What is the ionic equation,the spectator ions and the overall or net ionic equations?
This is done the same way as the Al + HCl problem above. Follow the template.
To determine the ionic equation, spectator ions, and overall or net ionic equation for the given chemical reaction, we need to first write out the balanced equation.
The given balanced equation is:
Mg + H2O → Mg(OH)2 + H2
To write the ionic equation, we need to split the reactants and products into their respective ions (if they are aqueous) and include their charges. In this case, Mg(OH)2 (magnesium hydroxide) is a strong base and dissociates completely in water.
The ionic equation for the given reaction is:
Mg + 2H+ + 2OH- → Mg2+ + 2OH- + H2
Next, we identify the spectator ions. These ions are present on both the reactant and product sides of the ionic equation but do not participate in the actual chemical reaction. In this case, the spectator ions are OH-.
Finally, to obtain the overall or net ionic equation, we eliminate the spectator ions from the ionic equation. After removing the spectator ions, we get:
Mg + 2H+ → Mg2+ + H2
Therefore, the net ionic equation for the reaction Mg + H2O → Mg(OH)2 + H2 is:
Mg + 2H+ → Mg2+ + H2
