When [H+] = 4.0 × 10–9 M in water at 25°C, then
Salsk061 [2.6K]

Answer:

a. Kw = 1.0 × 10⁻¹⁴

Explanation:

a. Let's consider the self-ionization of water.

2 H₂O(l) ⇄ H₃O⁺(aq) + OH⁻

The ion-product of water (Kw) at 25 °C is:

Kw = [H₃O⁺][OH⁻] = 1.0 × 10⁻¹⁴

c. Considering [H⁺] = [H₃O⁺] = 4.0 × 10⁻⁹ M, the concentration of OH⁻ is:

[OH⁻] = 1.0 × 10⁻¹⁴/[H₃O⁺] = 2.5 × 10⁻⁶ M

b. We can calculate the pOH using the following expression.

pOH = -log [OH⁻] = -log 2.5 × 10⁻⁶ = 5.6

d. We can calculate the pH using the following expression.

pH = -log [H⁺] = -log 4.0 × 10⁻⁹ = 8.4

Fittoniya [83]
When heat energy at a constant pressure = the change of enthalpy

ΔH = Q

and when the internal energy of an ideal gas formula is:

ΔH = n.Cp.ΔT

and when Cp = (5/2) R   at a constant pressure of a monatomic ideal gas

∴Q = n.(5/2).R.ΔT

∴ ΔT = Q / [n.(5/2).R]

when Q is the heat required = 43.08 J (given)

and n is no.of moles = mass / molar mass

                                  = 1.1 g / 39.948 g/mol

                                  =  0.0275 moles

and R is gas constant = 8.314472J/mol K

by substitution:

ΔT = 43.08 J / (0.0275moles *(5/2) * 8.314472 J/mol K

      = 76.76  K
