If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
This reaction is exothermic.
The reaction is endothermic.
This reaction is exothermic.
This is a precipitation chemical reaction.
The reaction produces heat
A white precipitate, that appears to be milky. Ca^2+(aq) + 2OH^-(aq) = Ca(OH)2 (s)
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
The reaction produces heat.
the apex one is ClO-(aq) + H2O(l) + 2e- - Cl-(aq) +2OH-(aq)
The ionic equation is 2K+(aq) + 2OH-(aq) + Co^2(aq) + 2Br^-(aq) ==> 2K+(aq) + 2Br-(aq) + Co(OH)2(s)net ionic equation is Co2+(aq) + 2OH-(aq) ==> Co(OH)2(s)So spectators are K+ and Br- ions.
H2C4H4O6(aq)+2OH−(aq)→C4H4O62−(aq)+2H2O(l)
the reaction produces heat
This reaction is exothermic.
the reaction produces heat
Write the ionic and net ionic equations and it turns out there is no reaction.Ca^2+(aq) + 2OH^-(aq) + 2NH4^+(aq) + SO4^2-(aq) ==> Ca^2+(aq) + SO4^2-(aq) + 2NH4^+(aq) + 2OH^-(aq) ... ionic equation.NOTE: all species are soluble, therefore NO REACTION
THE REACTION IS ENDOTHERMIC
