The mass of 7,346 moles of Ca(OH)2 is 544,3 g.
2 moles of Ca and 4 moles of OH

CaOH2 is a base because calcium is compounded with hydroxide, rather than hydrogen. Most if not all acids' names begin with 'H', while most if not all bases' names end with 'OH'.
The oxide ion in CaO (O2-) is a very strong base, meaning it will easily take a hydrogen ion (H+) from a molecule. In water the oxide ion take a hydrogen ion from a water molecule, forming to hydroxide ions. O2- + H2O --> 2OH- In this reaction the oxide ion acts as a base and the water molecule as an acid, at least by the Bronsted-Lowry definition.
CaCl2 and H2O
Calcium Hydroxide, or CaOH2, is a base. Generally compounds containing hydroxyl groups and metals will act as bases in reaction.
NaOH+CaCO3
Laboratory preparation of ammonia or NH3 requires using ammonium chloride and calcium hydroxide. The reaction equation is 2NH4Cl plus CaOH2 gives the products 2NH3 plus CaCl2 plus 2H2O. The ammonium chloride and calcium hydroxide are heated for this reaction.
Nope... it is not.
A white precipitate, that appears to be milky. Ca^2+(aq) + 2OH^-(aq) = Ca(OH)2 (s)

Calcium hydroxide.
You will need water for the reaction to take place. CO2(g)+H2O(l)--> H2CO3(aq) NOW IT IS BALANCED CaOH2(s)+H2CO3(aq) --> CaCO3(s)+2H2O(l)
Ca(OH)2(aq) + HNO3(aq) --> H2O(l) + Ca2+ (aq)+ NO3- (aq) Volume of Ca(OH)2 = 22.0mL = 0.022L Volume of HNO3 = 40.0 = 0.04L Molarity = moles of solute/Volume of solution M = .06/0.062 = 0.9677 M of Ca(OH)2

Acid. It's actually a base (calcium hydroxide) sometimes called "slaked lime".
