Conduction electrons and positive metals ions
Answer:
<u></u>
Explanation:
<u>1) Chemical equilibrium</u>
- 2Hg (l) + O₂ (g) ⇄ 2HgO (s) (the double arrow indicates an equilibrium reaction)
<u />
<u>2) Equilibrium constant, Kc:</u>
- The equilibrium constant, Kc, is equal to product of the concentrations of each product,each raised to its stoichiometric coefficient / product of the concentrations of each reactant each raised to its stoichiometric coefficient.
- Since the concentrations of liquid and solid substances remain practically constant, their value is incorporated into the constant Kc, and the equation only uses the concentrations of the aqueous or gaseous substances.
Thus, the equation to use is:
<u>3) Determine the concentration of O₂ (g)</u>
- M = number of moles / volume in liters
- Number of moles = mass in grams / molar mass
- Number of moles of O₂ (g) = 13.4 g / 32.00 g/mol = 0.419 mol
- M = 0.419 mol / 5.2 liter = 0.0806 mol / liter = 0.0806 M
<u>4) Compute Kc</u>
- Kc = 1 / 0.0 806 M = 12.4 M⁻¹ ← answer
Answer:
3. atoms, ions, or molecules
Explanation:
A crystal is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
Hope this helps!
