A stable arrangement of eight valence electrons : ³⁵Cl⁻¹
<h3>Further explanation</h3>
Chlorine is a halogen gas, located in group 17, p block
Chlorine has an atomic number of 17 and an atomic mass of 35
Electron configuration: [Ne] 3s²3p⁵
If we look at the electron configuration, then Cl will bind 1 more electron so that the configuration is stable like Argon (atomic number 18)
So by binding this one electron, chlorine forms negative ions (anions)
³⁵Cl⁻¹
B. Cl⁻² binds 2 electrons, exceeding the octet rule
C. Cl⁺¹, releases 1 electron, remains unstable
D. Cl, the neutral form of Cl, is still unstable with a 7-electron valence configuration

Answer:
My role models are my parents. They are my pillars of strength. They are my guide and give me the courage to battle obstacles in life.
My mother, being a working professional, manages all her work perfectly and with efficiency.
My father goes to office, but still does not forget to help me with my studies. They always encourage me in every aspect and motivate me even when I do not succeed.
My mother always smiles, no matter what the circumstances are and that gives me the strength and inspiration to face all problems.
My parents have made me understand what life is about and how to find that little ray of happiness in difficult situations.
What I am today and what I will become in future involves the support and affection of my parents. They have made me disciplined, dedicated and sincere.
A role model does not have to be a famous personality. It can be anyone who makes us believe in ourselves.
My parents fill sweetness in my life. From childhood I have learnt everything from my parents.
Not just parents, I also consider my teachers as role models. Even they guide me and show the path of success.
They have turned me into a fighter in the war of life
Answer:
1.9 x 10⁻¹³M
Explanation:
Given 0.027M Ca(OH)₂(aq) => 0.027M Ca⁺²(aq) + 2(0.027M) OH⁻(aq)
2(0.027M) OH⁻(aq) = 0.054M OH⁻(aq).
from [H⁺][OH⁻] = 1 x 10⁻¹⁴ at STP Conditions (0°C, 1Atm)
∴{H⁺] = [H₃O⁺] = (1 x 10⁻¹⁴/0.054)M = 1.85 x 10⁻¹³M or 1.9 x 10⁻¹³at 0°C & 1Atm pressure.
