Answer:
I believe it;s the difference in pressure
Explanation:
This is caused by the diaphragm contracting and therefore expanding the thoracic cavity. This increase in volume causes a decrease in pressure.
In emergency situations, the Assess, Recognize, and Care idea is a systematic and continuous technique for quick assessment, precise recognition, and prompt care. Because the health of an acutely ill patient can quickly deteriorate, frequent assessment, recognition, and care are essential.
<h3>What are the steps of which includes assess, recognize and care?</h3>
- Use a visual assessment to determine the need for further resources, evaluate safety, and form an initial impression of the patient
- A responsiveness check
- If the patient is not responding, open the airway while simultaneously testing for breathing and a pulse.
- After you've finished your quick assessment, give care in accordance with the circumstances discovered.

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>
