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>
Answer: d. all of the above.
Explanation:
Answer:
d. left ventricle
Explanation:
Heart consists of four chambers: left atrium, right atrium, left ventricle and right ventricle. The atria are located above the ventricles and their function is to pump blood to the ventricles.
Right ventricle pumps the deoxygenated blood to the lungs via pulmonary artery. Pulmonary vein brings back oxygenated blood from lungs to the left atrium. From here the blood is sent to left ventricle. Left ventricle pumps blood to the entire body via aorta. Since it has to make blood reach to every part of the body from head to toes, it generates maximum pressure. Therefore, left ventricle also has thickest heart muscles.
The conscious client was admitted to the emergency department with an overdose of the anxiolytic alprazolam (Xanax). The nurse implement first prepare to administer an emetic with activated charcoal.
Chemicals can be captured in the pores of activated charcoal. In order to treat some poisons that have been ingested, it is normally administered orally. For additional purposes, the evidence is scant. Peat, coal, wood, coconut shells, or petroleum can all be used to make charcoal. Charcoal is heated in the presence of a gas to create activated charcoal. The charcoal develops numerous interior pores as a result of this process. Activated charcoal may trap pollutants thanks to its pores. To treat poisoning, activated charcoal is frequently employed. Additionally, it is claimed to treat excessive cholesterol, hangovers, and upset stomach, but the majority of these applications lack solid scientific backing.
Hence, activated charcoal is good adsorbent.
