Look at the balanced symbol equation:
Mg(s)+2HCl(aq)→MgCl2(aq)+H2(g) \text{Mg(s)} + 2\text{HCl(aq)} \rightarrow \text{MgCl}_2\text{(aq)} + \text{H}_2\text{(g)} Mg(s)+2HCl(aq)→MgCl2(aq)+H2(g)What does the state symbol (aq) represent in this equation?
Aqueous (dissolved in water)
Acidic
Aqua
Alkaline
