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)

Which statements describe a closed circuit? Check all that apply.
ehidna [41]

Answer:

The answers are options A, D and E

Explanation:

Shut circuit implies a total electrical association around which flow streams or courses. When you have a progression of electrical wires interfacing with one another and finishing a circuit so flow goes from one end of the hover to alternate, this is a case of a shut circuit. A broken wire or an "open" (off) switch both leave holes in a circuit keeping electrons from going from one side of the power source to the next. In this way, electrons won't stream. This circumstance is called an open circuit. A shut (on) switch implies that the circuit through the switch is connected.The meaning of an open circuit is a broken way for an electrical flow because of an open switch or frayed wire. A case of an open circuit is a string of electric lights that don't work on the off chance that one globule goes out. YourDictionary definition and utilization precedent. Shut circuit implies an entire electrical association around which flow streams or circles. When you have a progression of electrical wires associating with one another and finishing a circuit so flow goes from one end of the hover to alternate, this is a case of a shut circuit.
