When calcium hydroxide reacts with carbon dioxide, calcium carbonate and water are produced. The balanced chemical equation for the reaction is: Ca(OH)2 + CO2 -> CaCO3 + H2O. To balance, make sure the number of atoms of each element is the same on both sides of the equation.
Calcium hydroxide.
In the given reaction 2HF + Ca(OH)2 -> CaF2 + 2H2O, HF is the acid (hydrofluoric acid) and Ca(OH)2 is the base (calcium hydroxide). The reaction forms CaF2 (calcium fluoride) and 2H2O (water) after the acid-base neutralization reaction.
The products of the reaction between Na2CO3 (sodium carbonate) and Ca(OH)2 (calcium hydroxide) are NaOH (sodium hydroxide) and CaCO3 (calcium carbonate).
The balanced chemical equation is Ca(OH)2 + Na2CO3 + 2HNO3 → Ca(NO3)2 + 2NaOH + CO2 + H2O
CaCl2 and H2O
Yes, Ca(OH)2 is a strong base. When it dissolves in water, it releases hydroxide ions (OH-) which can accept protons to form water, making the solution basic.
Nope... it is not.

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.
The balanced chemical equation is Ca(OH)2 + Na2CO3 + 2HNO3 → Ca(NO3)2 + 2NaOH + CO2 + H2O
The coefficients that correctly balance the equation CaO + H2O -> Ca(OH)2 are: CaO + 2H2O -> Ca(OH)2. Two water molecules are needed to react with one calcium oxide molecule to form one calcium hydroxide molecule.
The reaction shows calcium ions (Ca2+) reacting with hydroxide ions (OH-) to form solid calcium hydroxide (Ca(OH)2) and release heat of 16.71 kJ. This reaction is exothermic, as indicated by the negative enthalpy change.
