Answer:
14.8% of H2O2
Explanation:
Based on the redox reaction of H2O2/MnO4- is:
2MnO4- + 5H2O2 + 6H+ ⇄ 2Mn2+ + 5O2 + 8H2O
<em>2 moles of KMnO4 react with 5 moles of H2O2</em>
<em />
To solve this question we need to find the moles of KMnO4 until reach the endpoint. Using the balanced reaction, we can find the moles of H2O2 that must be converted to grams using its molar mass -Molar mass H2O2: 34.015g/mol-:
<em>Moles KMnO4:</em>
0.0297L * (1.4686eq/L) = 0.04362eq MnO4- * (1mol / 5eq) = 0.008723 moles MnO4-
<em>Moles H2O2:</em>
0.008723 moles MnO4- * (5mol H2O2 / 2mol MnO4-) = 0.02181 moles H2O2
<em>Mass H2O2:</em>
0.02181 moles H2O2 * (34.015g/mol) = 0.7418g H2O2
<em>%:</em>
0.7418g H2O2 / 5.0mL * 100
<h3>14.8% of H2O2</h3>
Neisseria gonorrhoeae is treated with a combination of drugs because the organism is resistant to many, including penicillin and fluoroquinolones.
Gonorrhoeae is a contender to produce an incurable illness due to the development or acquisition of resistance mechanisms for sulfonamides, penicillins, tetracyclines, ciprofloxacin, and more recently azithromycin and ceftriaxone during the past 80 years.
The Neisseria gonorrhoeae bacteria is the source of the sexually transmitted illness (STD) known as gonorrhea. The urethra in both men and women as well as the cervix, uterus, and fallopian tubes in women are all affected by N. gonorrhoeae infection.
Penicillin is the first drug that has been shown to be effective against syphilis and gonorrhea. However, compared to the dosage required to treat syphilis, which is often approximately 1,000,000 units, the drug used to treat gonorrhea is frequently administered in doses of just around 100,000 units.

Answer:
C. Au q4h
Explanation:
I calculated it logically
Answer:
The mechanism of by which kidney forms dilute or concentrated urine is based on the amount of ADH( Antidiuretic hormone) present in the blood. Collecting duct have receptors for the binding of ADH hormone.
Formation of concentrated Urine:
When the ADH hormone binds to the receptors present on the cells of collecting duct it open the water channels present on it. Once the water channel is opened the duct becomes permeable to water and reabsorption of water takes place in the body making urine concentrated.
Formation of diluted urine:
When ADH is not secreted in the blood, the collecting duct remains impermeable to water molecules which results in production of diluted urine. This happens when blood contains sufficient water.
