calcium chloride +water
The calcium salt of the acid used and carbon dioxide.
Ca(OH)2 (calcium hydroxide) is a strong base (which means it cannot be an acid). It is formed by mixing CaO (quicklime, or calcium oxide) with H2O (water).
I assume you mean the equation of this neutralization reaction. Ca(OH)2 + H2SO4 -> CaSO4 + 2H2O As usual, a salt and water are produced.
alkali
Calcium hydroxide would be a base. It would dissociate into Ca2+ and two OH- ions when dissolved into water.
