Is that supposed to say 200/2.00??
Answer:
0.0900 mol/L
Explanation:
<em>A chemist makes 330. mL of nickel(II) chloride working solution by adding distilled water to 220. mL of a 0.135 mol/L stock solution of nickel(II) chloride in water. Calculate the concentration of the chemist's working solution. Round your answer to significant digits.</em>
Step 1: Given data
- Initial concentration (C₁): 0.135 mol/L
- Initial volume (V₁): 220. mL
- Final concentration (C₂): ?
- Final volume (V₂): 330. mL
Step 2: Calculate the concentration of the final solution
We prepare a dilute solution from a concentrated one. We can calculate the concentration of the working solution using the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁/V₂
C₂ = 0.135 mol/L × 220. mL/330. mL = 0.0900 mol/L
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.
Higher temperature, more kinetic energy, more space between particles, higher volume
