Answer:
1.125 x 10⁻³.
Explanation:
- For the reaction: <em>2NO(g) + Cl₂(g) → 2NOCl(g).</em>
<em>Kc = [NOCl]²/[NO]²[Cl₂],</em>
Where, [NOCl], [NO], and [Cl₂] is the equilibrium concentration of NOCl, NO, and Cl₂.
∵ Initial concentration of NO and Cl₂ = 0.50 M.
<em>And the equilibrium concentration of NOCl = 0.30 M.</em>
<em />
∴ The equilibrium concentration of NO, and Cl₂: [NO] = [Cl₂] = 0.50 M - 0.30 M = 0.20 M.
<em>∴ Kc = [NOCl]²/[NO]²[Cl₂]</em> = [0.30]²/[0.20]²[0.20] = <em>1.125 x 10⁻³.</em>
Answer:
This would be sleet.
Explanation:
Sleet is formed when water droplets fall through a cold layer of air. Freezing rain, on the other hand, is water droplets that freezes upon contact with a solid surface.
Hope that helps!
Answer:
The correct answer is because the molecular structure.
Explanation:
The difficulty of ammonia and methane to be represented on paper is due to the molecular structure. These compounds have a three-dimensional projection with defined angles. Ammonia presents angles of 109.5º between the atom of Nitrogen and those of Oxygen. The ammonia presents 107.8º between the oxygen atoms.
In the methane molecule, there is 109.5º between the hydrogen molecules and the carbon atom. This results in the need for a 3D representation of the molecule.
Have a nice day!
