The chemical formula for the product is RbBr.
Answer:
A quantum of electromagnetic energy is called photon
Explanation:
A photon corresponds to an elementary particle that composes the light, without any internal structure that is known at the moment. Said particle carries visible, ultraviolet, infrared, X-ray, gamma and other forms of electromagnetic radiation particles. The photon can travel in a vacuum at a constant speed and lacks mass or electric charge.
Answer:
<u></u>
Explanation:
<u>1) Chemical equilibrium</u>
- 2Hg (l) + O₂ (g) ⇄ 2HgO (s) (the double arrow indicates an equilibrium reaction)

<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
