WRITE THE BALANCED CHEMICAL EQUATION,WRITE THE OVERALL IONIC EQUATION,IDENTIFY THE SPECTOR IONS AND POSSIBLE PRECIPITATES,WRITE THE NET IONIC EQUATION FOR mercury(II)chloride(aq)+potassium sulfide(aq)
You add the (aq) and (s)
HgCl2(aq) + K2S(aq) ==> HgS(s) + 2KCl(aq)
Now separate into ions but leave HgS(s) as the molecular form
Finally, cancel any ions that are common to both sides of the equation.
What is the balanced chemical equation for the reaction hcl(aq) + ca(oh)2(aq) cacl2(aq) + h2o(l)
