Correct.
The mass of 7,346 moles of Ca(OH)2 is 544,3 g.
2 moles of Ca and 4 moles of OH
The reaction between calcium oxide (CaO) and water (H2O) to form calcium hydroxide (Ca(OH)2) is a synthesis reaction. In this type of reaction, two or more reactants combine to form a single product. The equation can be represented as: CaO + H2O → Ca(OH)2. This reaction is also classified as a hydration reaction, as water is added to a solid compound.
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.
Nope... it is not.
Calcium hydroxide.
Calcium hydroxide.
Calcium hydroxide is written as Ca(OH)2 because the hydroxide ion (OH-) is a polyatomic ion composed of one oxygen atom and one hydrogen atom. In the compound, there are two hydroxide ions associated with one calcium ion, which is why it is written as Ca(OH)2 and not CaOH2.
CaCl2 and H2O
In one mole of this solution, there are seven moles of H2O.

Ca(OH)2 and Na2O
Calcium Hydroxide, or CaOH2, is a base. Generally compounds containing hydroxyl groups and metals will act as bases in reaction.
