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)

Suppose NAD is unavailable because NADH cannot be oxidized due to a mutation in the NADH dehydrogenase (Complex I). If FAD could
Dovator [93]

Answer:

FAD substitution will produce 28 ATP instead of 36.

Explanation:

NAD and FAD are coenzymes involved in reversible oxidation and reduction reactions. These compounds are also known as electron carriers. However NADH produce 3 electrons in electron transport chain and FADH2 produce 2 electron beacuase it transfer the electrons to second complex in ETC.

Normal prduction of ATP from glucose;

2 cytoplasmic NADH formed in glycolysis         Each yields 2 ATP   +4

2 NADH formed in the oxidation of pyruvate Each yields 3 ATP         +6

2 FADH2 formed in the citric acid cycle         Each yields 2 ATP         +4

6 NADH formed in the citric acid cycle             Each yields 3 ATP         +18

2 ATP from glycolysis                                                                                   +2  

2 ATP from citric acid cycle                                                                          +2                            

                                                                    Net yield ATP +36

C6H12O6 + 6 CO2 + 36 ADP + 36 Pi ⇒6 CO2 + 6 H2O + 36 ATP

If we replace the NAD with FAD the total ATP production would be.

2 cytoplasmic FADH2 formed in glycolysis          Each yields 2 ATP            +4

2 FADH2 formed in the oxidation of pyruvate   Each yields 3 ATP    +4

2 FADH2 formed in the citric acid cycle            Each yields 2 ATP    +4

6 FADH2 formed in the citric acid cycle                  Each yields 2 ATP   +12

2 ATP from glycolysis                                                                                    

+2

2 ATP from citric acid cycle                                                                            +2

                                                                  <u>Net yield ATP +28</u>

C6H12O6 + 6 CO2 + 28ADP + 28 Pi ⇒6 CO2 + 6 H2O + 28 ATP

An example of gaining potential energy
aleksandr82 [10.1K]

Answer:

An example for gaining potential energy would be: A glass bottle on the top of a high shelf would have more high potential energy than a glass bottle on the middle or bottom shelf because it has a long way or more farther to fall down or brake.

Explanation:

Remember Potential Energy is the restored energy of an object has.

I hope this helps you!
