<span>The correct answer is b. Radon. Oxygen, Hyrdrogen, and Boron, are not radioactivel ike Radon and it regenerates quickly meaning that even though it has a short half-life period, it stays for a long time once released. It also has no taste so it's difficult to notice without proper gear because you can't feel it.</span>
The bond between the 2 Cl atoms in a Cl₂ molecule is a covalent bond.
to break this covalent bond, energy is required.
when new bonds form, energy is released as the bond formation makes the molecule stable. molecules with low energy levels are usually stable.
To break the covalent bond, energy is required in other words energy is absorbed.
therefore to break the covalent bond in Cl₂ molecule
1)energy is absorbed
Answer:
Kb = [OH⁻] . [C₃H₉NH⁺] / [ C₃H₉N ]
Explanation:
The equation for the reaction of trimethylamine when it is dissolved in water is:
C₃H₉N + H₂O ⇄ C₃H₉NH⁺ + OH⁻ Kb
1 mol of trimethylamine catches a proton from the water in order to produce trimethylamonium.
It is a base, because it give OH⁻ to the medium
Expression for Kb (Molar concentration)
Kb = [OH⁻] . [C₃H₉NH⁺] / [ C₃H₉N ]
