Answer:
Positive feedback
Explanation:
If the temperature on Earth starts to lower then a "positive feedback" will start to begin trying to make Earth heat up.
Answer is: pH of monoprotic weak acid is 3.28.
Chemical reaction:
HA(aq) ⇄ A⁻(aq) + H⁺<span>(aq).
c(monoprotic acid) = 0.23 M.
Ka = 1.2</span>·10⁻⁶.
[A⁻] = [H⁺<span>] = x.
</span><span>[HA] = 0.23 M - x.
</span>Ka = [A⁻]·[H⁺] / [HA].<span>
</span>1.2·10⁻⁶ = x² / (0.23 M - x).
Solve quadratic equation: [H⁺] = 0.000524 M.
pH = -log[H⁺].
pH = -log(0.000524 M).
<span>pH = 3.28.
