Answer:

D.)Most of the mass of an atom is located in the nucleus.

Explanation:

Rutherford conducted his famous gold foil experiment which refined our understanding of the structure of an atom. Through the experiment he observed that when positively charged alpha particles were bombarded against a thin gold foil, majority of them passed through the foil undisturbed whereas a small percentage retraced their path.

There were two main conclusions:

-Since most alpha particles simply passed through undeviated this suggested that majority of the space inside the atom is empty

- Also, since some of them completely bounced back this suggested that there is a positively charged core in which the mass of the nucleus is concentrated.

The temperature of the gas is proportional to the average kinetic energy of its molecules. Faster moving particles will collide with the container walls more frequently and with greater force. This causes the force on the walls of the container to increase and so the pressure increases.

Problem PageQuestion A chemist makes of magnesium fluoride working solution by adding distilled water to of a stock solution of
igomit [66]

Answer:

5.37 × 10⁻⁴ mol/L

Explanation:

<em>A chemist makes 660. mL of magnesium fluoride working solution by adding distilled water to 230. mL of a 0.00154 mol/L stock solution of magnesium fluoride in water. Calculate the concentration of the chemist's working solution. Round your answer to 3 significant digits.</em>

Step 1: Given data

  • Initial concentration (C₁): 0.00154 mol/L
  • Initial volume (V₁): 230. mL
  • Final concentration (C₂): ?
  • Final volume (V₂): 660. mL

Step 2: Calculate the concentration of the final solution

We want to prepare a dilute solution from a concentrated one. We can calculate the concentration of the final solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁ / V₂

C₂ = 0.00154 mol/L × 230. mL / 660. mL = 5.37 × 10⁻⁴ mol/L
