For the reaction
Veronika [31]

I₂ (g) + Br₂ (g) ↔ 2IBr (g)

Given is Kc = 280 at 150 degree C.

Kc = [IBr]² / [I₂][Br₂]

Initially [IBr] = 0.45 / 2 = 0.225 M

The actual reaction is:

2IBr ↔ I₂ + Br₂, Kc = 1/280 = 0.00357142

In equilibrium,

[IBr] = 0.225 - 2x

[I₂] = x

[Br₂] = x

By substituting the values we get,

K = [I₂] [Br₂] / [IBr]²

0.00357142 = x×x / (0.225 - 2x)²

√(0.00357142) = x / (0.225 - 2x)

0.0597613 (0.225 - 2x) = x

0.01344 - 2 × 0.0597613x = x

(1 + 2 × 0.0597613)x = 0.01344

x = 0.01344 / (1+2 × 0.0597613)

x = 0.01344 / 1.1195226

x = 0.012005

Substituting the values we get,

IBr = 0.225 - 2 × 0.012005 = 0.17698 M

I₂ = x = 0.012005 M

Br₂ = 0.012005 M

Ultra Clorox bleach is 6.68% sodium hypochlorite in water. How much of each is needed to make an 800.mL bottle?
sweet-ann [11.9K]
If we have 6.68% NaClO, it is the same as saying--> 6.68 grams NaClO= 100 mL of solution. we can use this as a conversion. 

800. mL (6.68 mL/ 100 mL)= 53.4 mL

solution = solute + solvent

solute= NaClO
solvent= H2O

solvent= 800-53.4= 747 mL of H2O

so, we you need 53.4 mL of NaClO and 747 mL of water or 53.4 grams of NaClO and 747 mL of water

Part A Which acid in each of the following pairs has the stronger conjugate base? Match the words in the left column to the appr
vichka [17]

Answer:

HF

H₂S

H₂CO₃

NH₄⁺

Explanation:

<em>Which acid in each of the following pairs has the stronger conjugate base?</em>

According to Bronsted-Lowry acid-base theory, <em>the weaker an acid, the stronger its conjugate acid</em>. Especially for weak acids, pKa gives information about the strength of such acid. <em>The higher the pKa, the weaker the acid.</em>

<em />

  • Of the acids HCl or HF, the one with the stronger conjugate base is HF because it is a weak acid.
  • Of the acids H₂S or HNO₂, the one with the stronger conjugate base is    H₂S  because it is a weaker acid. pKa (H₂S) = 7.04 > pKa (HNO₂) = 3.39
  • Of the acids H₂CO₃ or HClO₄, the one with the stronger conjugate base is H₂CO₃ because it is a weak acid.
  • Of the acids HF or NH₄⁺, the one with the stronger conjugate base is NH₄⁺ because it is a weaker acid. pKa (HF) = 3.17 < pKa (NH₄⁺) = 9.25
