Answer:
- 0.07 °C
Explanation:
At constant pressure and number of moles, Using Charle's law
Given ,
V₁ = 439 mL = 0.439 L ( 1 L = 0.001 mL )
V₂ = 0.378 L
T₁ = 317.15 K
T₂ = ?
Using above equation as:
The conversion of T(K) to T( °C) is shown below:
T( °C) = T(K) - 273.15
So, <u>T = 273.08 - 273.15 °C = - 0.07 °C</u>
Answer:
That leaves us with: 1s2 2s2 2p6 And that is the electron configuration for F- , the Fluoride ion.

Electrolyte for the electrolysis is copper(II) sulfate
CuSO₄ = Cu²⁺ + SO₄²⁻
the reaction at the negative electrode
(cathode -) Cu²⁺ + 2e⁻ = Cu⁰
and...
(anode +) 2H₂O - 4e⁻ = O₂ + 4H⁺
The correct answer should be option C. hope this helps
