Write the total ionic equation for the reaction of hydrofluoric acid with potassium hydroxide. 1. koh(aq) hf(aq) → kf(s) h2o(ℓ)

2. k (aq) oh−(aq) hf(aq) → k (aq) f−(aq) h2o(ℓ) 3. koh(s) h (aq) f−(aq) → k (aq) f−(aq) h2o(ℓ) 4. k (aq) oh−(aq) h (aq) f−(aq) → k (aq) f−(aq) h2o(ℓ) 5. koh(aq) hf(aq) → kf(aq) h2o(ℓ) 6. k (aq) o2−(aq) h (aq) h (aq) f−(aq) → k (aq) f−(aq) o2−(aq) 2 h (aq) 7. k (aq) oh−(aq) h (aq) f−(aq) → kf(s) h2o(ℓ)

2. HF(aq) + K^(+)(aq) +OH^(-)(aq) → K^(+)(aq) + F^(-)(aq) + H_2O(ℓ)

<em>Step 1</em>. Write the <em>molecular equation </em>

HF(aq) + KOH(aq) → KF(aq) + H_2O(ℓ)

<em>Step 2</em>. Write the <em>total ionic equation </em>

HF and H_2O are <em>weak electrolytes</em>, so we write them as <em>molecules</em>.

HF(aq) + K^(+)(aq) +OH^(-)(aq) → K^(+)(aq) + F^(-)(aq) + H_2O(ℓ)

Explanation:

An open-loop system is a a group of related objects or systems that cannot send out or receive feedback and modify themselves.

  • It is a non-feedback system.
  • In this system, the output control system has no effect on whatever input that is fed into the system.
  • Output and input in such systems are independent of one another.
