Question 6 1.75 pts The following reaction 2H2S(g)=2H2(g)+S2(g), Kc=1.625x10-7 at 800°C is carried out at the same temperature w
kirza4 [7]

Answer:

[S₂] = 1.27×10⁻⁷ M

Explanation:

2 H₂S(g) ⇄ 2 H₂(g) + S₂(g), Kc=1,625x10⁻⁷

The equation of this reaction is:

1,625x10⁻⁷ = \frac{[H_2]^2[S_2]}{[H_{2}S]^2}

The equilibrium concentrations are:

[H₂S] = 0,162 - 2x

[H₂] = 0,184 + 2x

[S₂] = x

Replacing:

1,625x10⁻⁷ = \frac{[0,184+2x]^2[x]}{[0,162-2x]^2}

Solving:

4x³ + 0,736x² + 0,033856x - 4,3x10⁻⁹

x = 1.27×10⁻⁷

Thus, concentration of S₂ is:

<em>[S₂] = 1.27×10⁻⁷ M</em>

Ca(OH)2 is added to a large beaker. How is the solution different from the original water?
shepuryov [24]
Definitely, the correct answer is option B. When Ca(OH)2 is added into a beaker, the solution will turn into pink when the indicator phenolphthalein is added. This is due to the hydroxide ions from the calcium hydroxide dissolved in water. The compound dissociates into calcium ions and hydroxide ions.
