Solid calcium oxide and gaseous water are formed by the decomposition of solid calcium hydroxide . write a balanced chemical equation for this reaction.

The balanced chemical equation for the reaction is

Ca(OH)₂(s) → CaO(s) + H₂O(g)

From the question,

We are to write a balanced chemical equation for the decomposition of solid calcium hydroxide to give solid calcium oxide and gaseous water.

First, let us write the chemical formulas for the reactant and products in the reaction

Calcium hydroxide - Ca(OH)₂

Calcium oxide - CaO

Water - H₂O

Now, for the balanced chemical equation for this reaction

The balanced chemical equation for the reaction is

Ca(OH)₂(s) → CaO(s) + H₂O(g)

Hence, the balanced chemical equation for the reaction is Ca(OH)₂(s) → CaO(s) + H₂O(g)

A chemical reaction is said to be balanced if all the chemical species involved in left side of the reaction arrow are equal to right side.  

Calcium hydroxide has molecular formula it decomposes to solid calcium oxide CaO and gaseous water as follows:

The above reaction is a balanced chemical reaction because number of calcium, hydrogen and oxygen atoms are same on both side of the reaction arrow.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
