How do you write out and balance calcium hydroxide reacts with hydrogen chloride to produce calcium chloride and water

 Ca(OH)₂ + 2HCl →  CaCl₂ +  2H₂O

Explanation:

Reactants;

     Calcium hydroxide = Ca(OH)₂

     Hydrogen chloride  = HCl

 Products;

       Calcium chloride  = CaCl₂

        Water  = H₂O

The reaction equation:

           Ca(OH)₂ + 2HCl →  CaCl₂ +  2H₂O

The reaction is a neutralization reaction where acids reacts with bases to produce salt and water only.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
