Imidazole is a commonly used base in organic chemistry. While imidazole contains two nitrogens, only one of them is significantly basic. Using your chemical intuition, predict the more basic nitrogen.

Answers

Answer:

See explanation and image attached

Explanation:

The structure of imidazole is attached to this answer. The compound is colourless. The solid can be to dissolved in water leading an alkaline solution. Owing to the fact that imidazole possesses heteroatoms in an aromatic heterocycle it is classified as a diazole. The nitrogen atoms in imidazole are not adjacent to each other.

From the structure shown, we can see that the lone pair of the sp2 hybridized nitrogen atom is available because it is not part of the aromatic system of the heterocycle. This nitrogen is much more basic than the nitrogen atom attached to hydrogen whose lone pair becomes part of the aromatic sextet hence it unavailable for protonation and less basic.

It is summer and an 82-year-old woman is brought to you from her home after seeing her primary care doctor 2 days ago. She was started on an antibiotic at that time. Today, she comes to the emergency room not knowing where she is or what year it is. What could be a likely cause of this

Answers

This could have been a case of polymedication, but I doubt it since it is an 82-year-old woman. I'm not sure if they are antibiotics, but benzodiazepines and anticholinergic drugs can cause amnesia. Or, it is a possibility her primary care doctor gave her the wrong dosage of the antibiotics, causing side effects, one of them possibly being amnesia.

Answer:

According to the NHSLS, about _____ of men report always having an orgasm with their partner.

75 percent

Explanation:

Whereas 75% of the men reported having an orgasm with their partner, only 29% of the women experienced orgasm, according to the National Health and Social Life Survey (NHSLS) reports.  Female orgasm marks the climax of contraction of the vaginal walls or the general feeling of heightened warmth as a result of sexual stimulation.  It usually emanates from the pelvis, spreading throughout the entire female body with phases of sexual tension experienced during lovemaking.  Seminal fluids are also released at such lovemaking climax, especially by males.

17. Order: Humulin R 100 units IVPB in 500 mL NS infuse at 0.1 unit/kg/h
stat. The patient weighs 46 kg. How long will it take for the infusion of
this U-100 insulin to complete?

Answers

17) Calculation of time required for the infusion to complete.

            Rate(ml/hr) = Total volume(ml) / Time(hr).

               Time(hr) = Total volume(ml) / Rate(ml/hr).

        Calculation of volume(ml).

                 Formula = Desired dose/Dose in hand *Quantity.

       Ordered dose = 0.1 unit/kg/hr.

        Weight of the patient = 46 kg.

      Desired dose(D) for this patient = 0.1 * 46

                                                                      = 4.6 unit / hr.

                   Dose in hand(H) = 100 unit

                          Quantity(Q) = 500 ml.

    As per above formula

              Volume required = 4.6 / 100 * 500

                                          = 0.046 * 500

                                          = 23 ml.

            Rate = 23 ml /hr.

            Time(hr) = Total volume(ml) / Rate(ml/hr)

                           = 500/ 23

                           = 21.7

                           = 22 hr (Time required to complete the infusion).
