Answer:
The mass percentage of chlorine is 60.66 % chlorine in the compound sodium chloride.
Explanation:
Answer: The correct answer is <u>''fission</u>'' it occurs when a large nucleus is split apart.
Answer:
Explanation:
The given pH = 8.55
Unknown:
[H₃O⁺] = ?
[OH⁻] = ?
In order to find these unknowns we must first establish some relationship.
pH = -log[H₃O⁺]
8.55 = -log[H₃O⁺]
[H₃O⁺] = inverse log₁₀(-8.55) = 2.82 x 10⁻⁹moldm⁻³
To find the [OH⁻],
pH + pOH = 14
pOH = 14 - pH = 14 - 8.55
pOH = 5.45
pOH = -log[OH⁻]
[OH⁻] = inverse log₁₀ (-5.45) = 3.55 x 10⁻⁶moldm⁻³
The solution is basic because it has more concentration of OH⁻ ions compared to H⁺ ions.

Answer : Option C) It explained the odds of finding the position of an electron.
Explanation : Schrödinger's theory of the atomic model is true for the probability of finding the electron around the nucleus. Schrödinger used odd mathematical equations to describe the likelihood of finding an electron in a certain position around the nucleus. This atomic model was known as the quantum mechanical model of the atom. He posed an equation which is now called as the Schordinger’s Wave Equation, which incorporates both the wave-like and particle-like behaviors of electrons, which stated that electrons can act like waves/light and particles. Which later helped to develop the uncertainty principle for finding the probable position of the electron.
