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

In the reaction below green chlorine gas and brown iodine chloride forms yellow iodine trichloride Cl2 (g) + ICl (l) ⇌ ICl3 (s)
Keith_Richards [23]

Answer:

B. It will become more green and brown

Explanation:

Le Chateliers principle states that when a constraint such as change in concentration, volume, pressure or temperature is imposed on a reaction system at the equilibrium, the equilibrium position will shift in such a way as to annul the constraint. Let us see how this applies to the equation under consideration.

If the system is at equilibrium and more ICl3 is added to the system, the equilibrium will shift towards the left hand side (more reactants are formed). This implies that the colour of the system will become more green and brown since there are more reactants now in the system.

How are superheavy elements made?​
Julli [10]

Answer: Most methods for making new elements involve a cyclotron, which speeds up atoms to high velocities before they smash into other atoms—these atoms are usually of different elements. This causes the nuclei to combine, creating new heavier elements.
