Answer is: <span>concentration of NOCl is 3.52 M.
</span>
Balanced chemical reaction: 2NOCl(g) ⇄ 2NO(g) + Cl₂<span>(g).
Kc = 8.0.
</span>[NOCl] = 1.00 M; equilibrium concentration.
[NO] = x.
[Cl₂] = x/2; equilibrium concentration of chlorine.<span>
Kc = </span>[Cl₂] ·[NO]² / [NOCl].
8.00 = x/2 · x² / 1.
x³/2 = 8.
x = ∛16.
x = 2.52 M.
co(NOCl) = [NOCl] + x.
co(NOCl) = 1.00 M + 2.52 M.
co(NOCl) = 3.52 M; the initial concentration of NOCl.
Answer:
Sodium Hydroxide
Please mark me as brainlest because I have help you pleaseeeee.
Explanation:
Sodium hydroxide is a common proton acceptor also known as lye. It is the active ingredient in oven cleaners and drain cleaners because it can react with fats to produce compounds that dissolve in water. It is also used in many school laboratories to demonstrate acid-base reactions.
Answer:
Mercury is useful in lighting because it contributes to the bulbs' efficient operation and life expectancy. Fluorescent and other mercury-added bulbs are generally more energy efficient and last longer than incandescent and other equivalent forms of lighting.
Explanation:
Ca, V, Cu, Kr
Remember a period is a the horizontal rows in the Periodic Table.
